VSEPR = Valence Shell Electron Pair Repulsion.
According to VSEPR, molecular shapes are best understood as resulting from the fundamental electrostatic force (Coulombic repulsion) of electrons repelling each other. The valence shell electrons (the electrons furthest from the nucleus and the electrons participating in bonding) are usually in pairs, and these pairs of negatively charged electrons repel each other and try to get as far apart as possible.
The 5 basic molecular shapes are:
linear
bent
trigonal planar
trigonal pyramidal
tetrahedral

😁 thanks!!!!
i cannot wait until im done with chemistry
your done how do you fell
Mood
@@EightyBeat like I just finished learning something that has almost nothing to do with my field of study, BUT I also feel great knowing that I finished it.
bro...i got an exam in 4 hours
😂
I just learned more in this video than I have in 3 chemistry classes, thank you.
you're welcome!
WOW. Now it all makes sense! I was just crying because I couldn't understand my online chem class, and I feel like I learned more in watching two videos than I did all week studying and emailing my instructor. THANK YOU THANK YOU THANK YOU
Thank you so much, I didn't understand any of this in class wen my teacher explained it and now I actually understand how to do all this!
you're welcome :)
Me too
Someone tell me how a 12 min video was more clear than my professor's 2 hr lecture LMAOOOO
They might know what they are doing but can't convey what it is in words to their audience! I had a few like this!
Because there's no student talking over him
This is the most helpful chemistry channel ever on youtube!! Better explanation than any school or coaching teachers, trust me. You made my life a hell lot easier, thank you so much❤️❤️
glad it helped!
Yes I agree, my chem class or book didn't explain im glad i found this vid
Thank you! I have no clue why my professor had an over two hour long playposit when you explained it fast and simple!
Thank you a lot
Thank you a lot
Thank you a lot
Thank you a lot
I passed because of you
Gosh u just saved my entire AS education in a single video
You are making my life so much easier. If I could afford to give you money I would but sadly I'm a broke college student. One day I'll return the favor!
I was having a difficult time understanding this in Chemistry until I watched this video; it was better instruction than what my chemistry teacher gave me. I have a test on this topic soon, and I hope a receive a wonderful score!
me too it's on Tuesday! How did yours go?
@@puddleduck1405 I got an 83%, so it wasn't too bad. I also apologize for not responding to you for awhile. I was on Spring Break and I wanted to relax and clear my mind. However, regardless of that, I hope you got a good grade on your exam! What did you score? 😊
@@annieleonhart365 oooooh niece! Thats probably an A* cos the grade boundaries in chem r quite low. I haven't got it back yet haha, and I dont go back to school for another 2 weeks.
There's somethings that can't be left appreciated and this is one of them, I was reading my chemistry notes and I couldn't understand it but you gave me hope. So all I wanna say is Thank you Sir.
i couldn’t figure this stuff out for days and this video cleared it up instantly!!
nice!
Omg yaaasssss much needed video i love your videos !!! 🥰🥰🥰
Thanks Eloise!
thank you!! it seems my class didn't really go over this and my end of year exam is tomorrow ^^;
thanks for teaching me! it was quick and easy to understand, hopefully it'll come through tomorrow morning :)
Did it?
How did I understand this, maybe you speak perfect English. Lol
Why did CO2 become a double bonded pair instead of keeping 3 lone pairs around both Oxygens? Please answer
this channel has saved me more than id like to admit, this channel in 30 minutes has taught me more than my chem teacher has taught me all year (it's the end of april) thank you ketzbook!!
glad it helped! you're welcome!
can you PLEASE do hybridization, sigma and pi bonds? they’re so confusing
I'd like to, but I'm quite busy with my own teaching and now writing recommendations. Most of the videos I'm publishing now I made over the summer and am just editing and publishing now... I will keep this in mind.
@@ketzbook oh i see. thank you for considering it. and i really appreciate all your videos, they’ve helped me a lot! :)
10:40 timestamp for diagam
Thank u
Thank you a lot
Thank you a lot
Thank you a lot
Thank you a lot
I hope everyone will see this channel and learn chemistry in an easy way. keep up the good work @ketzbook respect+
thanks for the support!
Thank you very much. You make chemistry simple to understand!
Omg my braincells actually connected tysm
Oh my goodness, thank you! I was dying on Khan Academy with this topic. Appreciate the pep, clarity, repetition/summary, and especially your telling us up front why it matters.
thanks it's 3 am and i have a test tomorrow that i just found out about lmao
thank you for this video! i was confused in class and this was concise and helped so much
These tutorials help me understand chemistry better than with my lectures
the best video on the whole internet....
AYOO BROO. KEEP IT UP BRO...ITS THE BEST😱..SUBBED!
holy shimmy i needed this thank you
Best video of molecular geometry using animation!😊😊😊😊
thank you so much your the best
Omg omg thank you for this vid 😭😭😭😭😭😭 i srsly couldn't understand a word of vsepr theory and you made it look sooooo freaking eaassssyyyyy thank youuuu. Subscribed!!!!!
This is quite literally the most helpful video I’ve watched for chemistry Tysm dude
Hi sir, can you explain further related to geometrical shape of formaldehyde? Because according to what I learnt in school ,double bond is treated the same way as single bond, so it's actually trigonal planar with 120 degree.
This video is a life saver!
Thank you, everything was clearly explained in this video
You are a life saver, have a big exam tomorrow and didn’t understand this at all, thanks for the help, subscribed and liked!
Perfectly explained! Makes complete sense, I learned more here than from chemistry class.
Best tutor of all time!
thanks!
Thanks for making this video!! It helped me so much!!
منورين شباب
The mass of videos, textbooks, comments, books, and online postings associated with chemistry is a perfect example of how poorly taught, and terribly communicated this subject is. Most importantly I feel its given to address how chemistry really is underserved and the main deterrent as to why there are so few chemical engineers, chemists and nuclear engineers is because of how poorly taught and unnecessarily complicated it is. The educational system, especially in the United States isn't designed to teach something so dense and interesting as chemistry. It is really unfortunate that despite outsourcing to colleges, and higher learning institutions, students like myself still have to go out of our way to gather the information we need to succeed despite having paid for (in the US) tons of money just to go back to the dorm and watch videos and read on how these things work because the professors, educational institution, and learning format does not server the material. Anyways the rant is over. Fuck chemistry.
oops, looked at it wrong. Thanks, very helpful!
Very easy to understand!! V well explained!! Thank you!!!
SO2 has two double bonds, you need to make sure the formal charge on the individual atoms is 0.
as someone who wanted a quick review for orgo, this was actually so helpful. thanks!
I hate chem and i have exam tomorrow. Even though i watch a hundred times of thus i still can't focus and can't understand chem.😢
Chemistry is fucking simple. We just need the right teacher, the right animation and the right tricks.
According to internet: *five electron domains around central atom is trigonal bypramidal, six electron domainds around a central atom is octahedral* There also SUB shapes, like T-Shaped, etc.
well, the "internet" is not a real resource but a collection of many resources (some reliable, some not), but yes, in my next molecular geometry video I will include "expanded octet" shapes such as the ones you mentioned.
@@ketzbook When might you have this next video available?
Thank you so much, I have a good knowledge of everything right now
Can you please make a second video about the molecular geometry of non octet molecules and thank you for the GREAT explanation !!!
thanks, yes, I probably will eventually, but I have a lot of other vids I want to do first.
I can't thank you enough for this, finnaly got my concepts clear ❤
You really explained it so wellllll, you're a blessing😫🤧🥺❤.
Glad it was helpful!
This is in our review but we never even learned it :,) I’m gonna fail I have the exam in 10 minutes
Clear and concise info. The visuals are great. Thank you!
you're welcome!
Are you saying if all atoms can bond we can pass through stuff :0
LOL they didnt have videos like this when i got Ds in organic chem 1 and 2 20 years ago
What is the difference between molecular structure and molecular geometry
Where can I found the video on octahedral or dipyramidal .
Help please
Skip around until you find the flowcharts.
how can i animate a video like this?? need it for my peta due tomorrow.. :(
thank you so much! this was so helpful !
Thank you so much it’s so helpful 🥺❤️

Thank you so much for this video. we are doing these right now in Chem, so hard to think when we are looking at them 1 dimensional when all have different shaped! And how they pair!!! ❤
Glad it was helpful!
ur videos are sooo helpful. thank you soooo much!

Garcia William Jones Kimberly Allen Donna
i honestly dont understand anything i tried other vids and still dont understand
thank you very much this was helpful
This was incredibly helpful. Thank you so much!!
Glad it was helpful!
maybe i will pass chemistry... tysm
THANK YOU SO MUCHHHHH
I'm going to fail Chem 2 aaaand lose my job 🎉
❤️ , sir you explained it very well & so perfectly....... thank you so much
i love u
:)
Thank you so much, this video is really helpful, i'm so excited :))))
Great video! Just purchased the Pocket Chemist too!
i hope to pass organic chemistry class this time
this video has helped me the most by far in understanding VSEPR theory, I have a test in two days and was stressing out, now am a bit more calm
Great clarification. "Thing" approach really works. Thanks!
❤❤❤ oh wow, I will keep watching and learning through this your well explained and interesting video❤❤❤ oh I have a test coming up and this is one of the topics that are giving me problems, but I have found a solution to it! I thank you 🙏🙏♥️💥♥️♥️
Thanks very clear, Very helpful
You're welcome!
i cant do this
Thank u so much bro for giving this wonderful opportunity
This video is among the BEST I've found covering Molecular Geometry, thank you.
Thank you so much for this!
nice video, i live in the netherlands with a totally different method at school, but this one video is really helpfull, thanks again
1:57 why does sulfer need 8 valence electrons? why can't you keep it at 6?
Youre the GOAT chem teacher!
Bro thank you so much. really needed this to understand the shape of molecules👍
I found this to be very helpful thank you.. Keep up the good work
I got external exams coming and this is a life saver 😭💞💞💞
Thank u!!!
Thank uuu !!!
