You could be a rapper
Abdul Wahhab yes you are for sure
@@hennessy_aj i'm more concerned by it's lack of sense...
You should do a crash course in organic chemistry...Hank you are literally the greatest teacher I've ever had!
like haloalkanes and whatnot... a crash course on those would be so useful
They are doing one now!
“It’s either an ether or an ester, either ester or ether, ether or ester either one, one or the other, either ether or ester!” 😂 This had me cracking up, so thankful for Hank Greene🙏
I studied this in school in the whole past month, and now you made it all fit in a 8:37 minutes long video.
School is so boring, and even more boring and useless when there are good videos like this one.
still the depth your school is providing you while teaching you these stuff is important.
These are like..the very basics about a portion of hydrocarbon derivatives
@@Yuno08888 Wow!
I wrote this comment in my last year of high school, and now I'm in my last year of college, becoming a doctor in a few months..
Only god knows how bad I miss those school days 😢
Thank you for reminding me of this comment 😊
@@isa.sharif
I'm in my last year of highschool as well!
Hopefully i can become a doctor as well
Congratz dude I wish you all the best♥
Organic Chemistry is like a fun puzzle and a lot of wordplay. When I solve organic chemistry problems, I feel like I'm sherlock holmes or something XD
Have you studied all the reaction (example - Friedel crafts alkylation reaction, acetylation reaction, clemensen reduction reaction, bayer's test, wolf-kishner reaction, wurtz reaction, mozingo reduction)????????
having a BSc in chemistry, I could follow you without problems, but I can imagine others had to pause/rewind the video multiple times to understand it. Good of you to not explain things slowly, that is the magic of online videos! If you don't understand, just pause and rewind until you do!
Cadaverine? Sounds good for an extreme metal band.
I just love hank- whenever I start dozing off, he cracks a joke. " Methanol absolutely will kill you"
i like it when he said amino acids which make up protein which make up you which is pretty important. i have never felt so important i love you hank
when you talk,chemistry makes sense. i wish you taught at my school.
Same..... My teachers are nothing like this
5:20 - more than twice mate -__-'
It's nice that all the names of the functional groups are related. Nice, that is, once you UNDERSTAND the groups. On the other hand, it adds to the difficulty in learning their names, one of the biggest reasons many people struggle with organic chemistry, since they are so close that they are really, really easy to muddle in the brain, i.e. it takes a ton of brain work and repetition to keep those memory pathways separate instead of blurring into on big mush of carboalcoacetonahyde...
I'm in 9th Grade and using these videos to review for the finals. Very effective. Just drop me out of school and I'll watch these videos and I'll learn everything.
Hank was right if you watch it twice it makes a lot more sense
god, I am never gonna remember all this on my test tomorrow. Time to watch again.
Thank you so much once again to all the team for these videos, you make my chemistry classes fun and fascinating :)
Might be important to state that alcohols can be put in to three classifications: Primary, Secondary and Tertiary alcohols. This basically tells you how many radicals (Rs) are connected to the carbon that holds the important stuff (oxygen and hydrogen in this case), the functional group. When you dehydrogenate a Primary Alcohol you get an Aldehyde, which you then again can dehydrogenate to make a carboxylic acid. A secondary alcohol can be dehydrogenated into a Ketone, and a tertiary cannot be dehydrogenated at all. This might make it easier for some people to understand this topic, as it helps me. Also to clearly explain the primary and secondary bit: if there's only 1 radical (R) connected to the relevant carbon, it's a primary alcohol, if there are 2 radicals connected it's secondary and so on. it cannot exceed a tertiary alcohol though. Hope this helps someone! :)
can you not just say oxidised rather than dehydrogenating?
I don't know what a script supervisor does, but I always picture a stack of papers sprouting legs and trying to run off then that person grabbing it before it can get anywhere.
5:20 i swear if you watch this episode twice you will understand
That actually cracked me up
PERFECT TIMING
I sighed and decided to watch it again thats EXACTLYwhen he assured me !
I actually watched it thrice
he lied
seeing the connections between functional groups makes me so happy. i never saw this before. thank you 😭❤️
Do crash course quantum physics/mechanics.
I take a chemistry course in school and yet I don’t go into these videos with a revision session mindset. Instead I like to watch these out of curiosity. A wise man once said “you never learn something as profoundly as when it’s purely from curiosity”.
YESYESYES i have an exam tomorrow and this was literally the only thing i didnt understand.. love crashcourse!!
a-(5.6-dimethylbenzimidazolyl) cobamidcyanide........MAN that's a mouthful!
Reuel Teesdale of dis dick
malik tillman -_-
Reuel Teesdale But it's only VITAMIN B12 :(
Seriously had these all memoried after watching twice. And was quite entertained along the way. BRAVO
Hank, you made my heart smile when you said you were a dork. You are the cutest
Damn. Chemistry is beautiful.
you have an awesome pic :3
Axel493 (ಠ_ಠ) really nigga
Axel493 I like both your pictures kingdom hearts rocks
Andrei Stephen shut up scrub
umn kay then
I think his videos are amazing, I keep rewatching them just because I love the way he explains himself
Oh and you're explanation is really good keep going mate 😅
Flubber!
Robin Williams is everywhere and rightfully so.
3.44-2.20=1.22
Well done guys. This is how you math.
3.44-2.20=1.24* ;)
Nah, they made that mistake in the video, im just making. Fun of them xP
+lazerbeam3000 ohhh ok that's my bad xD
+lazerbeam3000 It's how I math xD
Lol!
Bless you, No seriously, BLESS YOU! Long live crash course!
I'm telling you hank you're ah literal life saver.. Thank you
Hank you're hilarious, I love functional groups too....watched it just for fun
Diggin' the Platoon of Power Squadron shirt!
This videos sums up the part of A-level Chemistry i was good at. After 4 years i want to find my old text books and see what i remember.
I wish I could be just as passionate and brilliant as you are :,(
actually a life saver thank you!
in our organic chemistry class, there's another functional group called amide.
First time the functional groups have made sense to me. Thank you.
There's also Amides. If you throw an Amine group onto the end of a carbonyl group (to replace the second R group) you get an Amide! :)
crash course chemistry, you are a beautiful thing. Saving my procrastinating butt on the day of an exam. Thank you for these videos.
This is exactly what we're doing currently at school. But this is so much more fun.
this guy is good!!!!!!!!!!!!! thumbs up man...... am definitely a fan, 1st year UNAM, this is my only backup.......

Much much better than the lectures I'm taking in college (y) when Hank explained aldehyde I was like OOOOOOOH now I seeee
Loveddddd ittttttt 😍❤️ I really understood what's a functional group is thanxxxx❤️❤️❤️
Cadaverine... wow. That's a good name for a death metal band.
I may or may not be partaking in a last minute cram session for my chem test tomorrow....
oh the memories of high school chemistry. i loved organic the most. i wish i could take it at uni, but it has one more extra chem prereq that i cant fit into my full schedule of math and physics courses
It was super fun for me too, Hank.
Thank you for saving my Ochem quiz grade
5:20 Watch episode twice, you will understand everything
Me*: Starts video from beginning
This video made me super excited for chemistry!!!!!
I took a sophomore-level uni organic chemistry class. And I usually understand all of the Crash Courses. And yet...I still don't understand organic chemistry. My brain is just like, "too many names! Too much jargon!"
You don't need to know all the names. Everything is about a system. This goes especially in organic compound names.
It's been years and I'm still waiting for a crash course series on organic chemistry
OMG I'm falling in love with organic chemistry:)
I love this, if I watch this a couple more times to understand organic chemistry, I would ace my test on it! Wonderful.
He said watch it again to understand it so I watched it again.
***** the ultimate question do you understand it now?
just the most rudimentary parts of it.
Nice work, Hope I remember to have my young cousins watch this with me.
The o in ketones is directly in the middle the word.
ketOnes
Aldehyde is on the side.
1:19 Yay! Trinitrotoluene!! Been waiting for that to make an appearance... :D
TnT huh
I love that this channel is subtitled so well. Both because you babble unbelievably quickly (assuming in order to meet time constraints) and because it helps me to read things as I learn them.
First video I'm watching. I'm a chemist and was thinking HOW did you make it 43 episodes without mentioning any compounds with elements besides carbon and hydrogen!?!
I love it how in the end of every video he says," If you were paying attention..."
Thanks again for such a great video, Hank.
this was super fun!
Crash course helps people pass their tests of free Amazing!!!!
Thanks for the videos Hank this is exactly what we need to know for my chemistry class right now
i need a new brain i just melted...
Strothy2 lol 😂
As I have studied chemistry for a while now, I am realizing some things this set of videos misses on... Any chance of an advanced chemistry crash course?
👆best idea
Wow. It really helps! Thanks crash course!
right over my head but i loved it
did he just summarize my 50-pages organic chemistry chapter?
God, I love crash course
THANK YOU THANK YOU THIS IS BEAUTIFUL.
when I was younger I was fascinated with how horribly toxic, poisonous or even radioactive atoms could be combined with other atoms of the same properties, such as cyanide then all of the sudden you get a vitamin or protein that is important for life.
Makes me wish I'd taken Organic Chemistry in school when I was taking random classes. While the basics were pretty straight forward, the terminology made my eyes water. Or maybe that was onions being chopped in the next room.
Pretty hardcore video (in a good way!), definitely worth another watch. Thanks!
Please do the lymphatic system !
wait... what?
isn't that in biology?
Willem Breukelaar Lol , It is !
Whats that got to do with this?
Ian Cameron he will read the comment whether its here or on a biology video .
crash course you should do a video on Madagascar since it's like a huge hit fossa looks like a cat but is actually a mongoose and how all life there evolved in isolation and things aren't always what they seem on the island that's what makes it unique
5:20 "I swear if you watch this episode twice, you will understand"
Watched twice, can confirm
Great Video, only there is a correction to be made because the difference between oxygen and hydrogen is 1.24. 3.44 - 2.20 = 1.24. But great help thank yoU!
I was confused way before the "IMPENDING CONFUSION ALERT"
3:55 carboxylic acid
Amines: Terminal NH2 group
Finally, I know what carboxylic acid is!
haha like how quickly he's talking cos it helps save a lot of time :)
1:22 2,4,6-trinitrotoluene TNT
awesome vid! :) a tad confusing...will watch again! :) Thank you!
I was mind blown at the aldehyde part because I was never taught that it is alcohol-dehydrogenated!
Yeah and the catalyst is Phosphoric acid!
So if you mix Coca Cola (Which has Phosphoric Acid) and Vodka, you'd probably make a small amount of Ethanal since the Ethanol in Vodka can react with oxygen in the air :/
A crash course on organic chemistry would help so many college students. It's so common for people to flunk out of that class or pass with barely a C.
We have good news for you! We made a 50-episode series on Organic Chemistry available here: ruclips.net/p/PL8dPuuaLjXtONguuhLdVmq0HTKS0jksS4
THIS IS AMAZING I SUDDENLY UNDERSTAND WHAT MY ORGO PROFESSOR TRIED TO TEACH ME FOR TWO WEEKS. THANK YOU.
I had to learn about these in organic chemistry :P useful, but not easy to do mechanisms for.
you are awesome hank
Crash Course , Please make a video about the preparations of Alcohols in Industries
0.o
My brain overclocked and had a melt down
Cool video
WHOA. So. An embarrassing number of years after I took organic chemistry, and even more years since I read Ender's Game, this video just made me realize where the Formics got their name. Thanks!
But what's up with that animation at 7:00? It looks more like a pilot whale who got too close to the Faroe Islands :(
B O I
As a die hard Nitrogen fan I'm disappointed in the lack of Nitrogen in this video. I hope we get more in the organic chemistry series
R = rest (fragment that we’re not concerned with. Functional group: where the business is getting done. Oxygen = delta minus. Hydrogen: delta plus.
