You are the real hero. I'm so glad that I discovered your channel before it was too late. (have the final on 16th of december and all the slides are in French, coz they just added organic chemistry to the program, polymer science master Strasbourg-Freiburg, and the only professor with terrible English teaches organic chemistry) you are my savior
It's neat to see your evolution over time. The science heavy teacher stuff is great. The no nonsense frank debunker stuff is great too. I look forward to another nine years and more of your lessons.
You see how you said chlorine has 6 valence electrons and aluminium has 4 valence electrons should the chlorine not be negative because it has more electrons. If not why is that? It's at 1:15
Random Help In the catalytic complex, chlorine will have a formal positive charge because it's showing 6 electrons in the lewis dot structure, one per bond and two lone pairs, compared to its typical valence of 7. One fewer electrons means a positive charge. Aluminum shows 4 electrons, one per bond. Its typical valence is 3 so this has a formal negative charge.
like if I had a question on the test that says to explain the mechanism of the reaction with the same catalytic complex that we used in the halogenation how would I know its not Friedle reaction? I know my question is kinda stupid but I have a test tomorrow and I am soooo nervous
If the benzene ring already has a substit. group on the ring that does not prevent the reaction, I'v been told that it adds to the meta position, is this correct?
the regioselectivity of an electrophilic aromatic substitution reaction on a monosubstituted ring depends on the identity of the substituent, check out my clip on o/m/p directors!
it's because friedel-crafts alkylation involves the formation of a carbocation on the alkyl fragment as an intermediate in the mechanism, and carbocations are highly unlikely to form on sp2 carbons.
+Uzumaki Saptarshi the oxygen interacts with the zinc atom to form an oxonium species, which is highly electronegative. this intermediate is what the arene reacts with.
He's gorgeous, definitely a close second to Dave. Unfortunately, Said just doesn't know enough Ochem to keep me watching him everyday. Dave doesn't have that problem; he's too busy solving mine!
Thank you so much! I'm a second semester organic chemistry student, and I've watched several of your videos to help me with homework and tests.
all hail chemistry jesus
thank you, my son.
HAAHAH so true :DDDD
A miracle worker indeed. You saved 3 organic courses of mine :P (pun intended). You show the one true path to graduation :P

Makes more sense to worship a worldly genius than a mythical sky god.

What are you doing now
currently pulling an all nighter for an o chem test tmrw at 8 am. just started watching your channel, you're the bomb!
Glenda Macco
Same here
Me too but a year later haha
Me too but 3 years later lmao
9am here
Best of luck 🙂😂
A legend was born
Thanks, Dave. Short and to-the-point.

woah,man,this is good. I told a coupla my friends already!
man I love chemistry, my school teacher told me not skip ahead with material as to not overwhelm myself, but I simply enjoy the subject
Not all heroes wear a cape. This is showing up on my exam next week and you just saved my ass. 👍 👍 👍
Pass the exam?
@@melancall5960 damn this was 4 years ago. I did pass and graduated almost 1.5 years ago 😂
@@IsmailAhmed_IshydadonHi pal, what are you pursuing now? I'm just curious
Who is here in 2024?
Yo
So, this is how the legend was born 🫡
And so, a legend was born
Humble beginnings.
I ma here before my exams 😭 thank you so much sir
Perfectly explained.Where have you been bro for all these years??
Teaching in the flesh! But now it's time to share the wealth with the people. Please spread the word!

thank you very much sir,I am a class 11 student and this video really helped me
That's a cool tattoo Professor Dave. Now I know how a parsec is defined!
You sir are a savior!
Extremely well done, Dont stop making more☺
Wah adey kya baat!
What are you doing now
@@atharvvohra3908kya kar rahe ho bhai
Realy helpful thx. I´m from germany and there was no problem understanding you. So well done !
Anyone an idea about the +M - effect ? Its relevant for my Test tomorrow.
Sir now u have 1million subs
🔥🔥🔥👍👍🙏
Keep it down👍👍👍
Yeah, because he can’t do anything apart from making yt vids.
Thank you so much you have NO idea how much your saving me right now
Awesome explanation , thanks for it
Short and to the point, i like it! Thank you!
All hail chemistry Muhammad. Just discovered the channel.Im learning so many new things . Thank you for taking the time out to post
Ur going to hell
Also, when is rearrangement needed for Electrophilic Aromatic Substitution?
Y amine doent undergo fridel craft alkylation? Is there any other compounds other than amine and phenol?
the group with a lone pair will interact with the lewis acid catalyst before the alkyl chloride has a chance to
You are coming from the last video
where does the H comes from at 2:45? that is also attached to the ring next to the alkyl fragment
every carbon in a benzene ring has one hydrogen, they are just implied unless needed for the mechanism
Stupid me ugh, thanks!
Why do we restore aromaticity? What is the significance?
Thanx prof.
All respect for u
Yor are reallly incredible and a lifesaver(THANK YOU) Although I do have a question: Does a multiple substitution happen here?
Good

You mean one lone pair right or there would be 8 valence electrons 0-0
thank you professor Dave
There was no music. wtf
i love the new intro
What's the limitations I don't get them do u have a video of them 😭😭 polyalkylation and carbocation rearrangement
Sir, what you are discussing is Friedel craft alkylation. Have you made any vedio on acylation?
yep, i did!
First video? 😮
but what is the difference between this and halogenation?
this is alkylation
like if I had a question on the test that says to explain the mechanism of the reaction with the same catalytic complex that we used in the halogenation how would I know its not Friedle reaction? I know my question is kinda stupid but I have a test tomorrow and I am soooo nervous
@@fatimaalkwndy9673 alkylation will require an alkyl chloride, so R-Cl + AlCl3 you know it is alkylation
thank u sssso much sir you're life savior
sir, do u have any videos that might help me with understanding the +m effect?
the mesomeric effect? hmm
@@Kurosakayeah
You are clutch, my good sir
Professor is a big lad.
thank you so much

What are hybrid orbitals of phenol amine tetra di phosphate ????
Thanks for the explanation, But i have a question. Why does the chloroalkene wants do bond with the AlCl3?
just a Lewis acid-base reaction! chlorine's got lone pairs, aluminum is electron-deficient.
What are you doing now brother
can we use Iodine in this
nope just chlorine
Hello Do you have a video for Friedel-Craft Acylation?
nope but it's essentially the same reaction just with an acid chloride instead of an alkyl chloride!
Thank you
why am I payin all this money for school and learn nothing but RUclips is free
you're the man
You are the besttttt love you my lifesaverrrrr
why hydroxylation take place at the end of Friedel craft acylation?
+Asif Khan Mohammad no hydroxylation, there's a carbonyl group that was already present in the acyl chloride.
I´m writing my exam from home while watching this xd
Love you prof ❤️
Nice ! My book had only 1 line n the figures n didnt understand but now after watching this i do !
Sir, and why can't Vinyl halides and Aryl halides undergo Friedel Crafts Alkylation..whereas...a double bond involving molecule like Acyl group..undergo Fridel Craft Acylation..??
it's because friedel-crafts alkylation involves the formation of a carbocation on the alkyl fragment as an intermediate in the mechanism, and carbocations are highly unlikely to form on sp2 carbons.
Thanks
helpful!
What's the difference of alkylation and aceylation
acylation adds an acyl group!
the question is how much should AlCl3 be used in this reaction?
1 on1
Can you make a video on acetylation?
i'll put it on the list!
Yes Please!
please use full representation its hard to understand those I'm not saying I don't know that but its easy the other way
i'm not sure what you mean.
nvm
@@ProfessorDaveExplains I think he means its diffucult to undestand the structure orbitally
This day marks the birth of Jesus
Sir, can u please do a video on Friedel Crafts Acylation??..it really is confusing ...only u can explain it in a crystal clear way...
it's very similar to the alkylation! you can google the mechanism and email me if you have any questions.
🎉
Can anybody explain me mechanism of Blanc chloromethylation?
+Uzumaki Saptarshi the oxygen interacts with the zinc atom to form an oxonium species, which is highly electronegative. this intermediate is what the arene reacts with.
