You can remember this as the PAD-PEAD(protonation,elimination,addition,deprotonation) mechanism.

[@senorsuraj8428]

Thank you so much! This made it so much easier to remember

[@Encrylius]

I wonder why my O chem professor never covered this? This is all over the MCAT and DAT thanks man!

[@Michelle-rv9ns]

Hey, is there a great mcat practice book you recommend? I'm taking it next year

[@ArielStar]

@@Michelle-rv9ns Kaplan is pretty solid

[@123magicT]

my ochem professor covering it and it goes hands in hand with my MCAT studying!!!

[@Jack-ky6ds]

The Villian studying ochem??? Incredible

[@AYUSHV602]

we have in 12the class😂😂

[@jeffsincich4852]

Hey your vids for algebra got me a 100% on a test thank you！

[@anhadrajkhowa5850]

JEE peeps take note, this question came in Mains 2021.

[@dhruvmishra415]

Thanks bhai

[@DeveshBhatt-vo6wl]

Thanks buddy❤

[@AparnaJEE2025]

Ok bro

[@shreyasiacharya8053]

It was really nice... Love from India ❤

Protecting group 7:23

[@Awesiim]

At 6:00 didn't you form a ketal and not an acetal since you started with a ketone?

[@taylorteehungpiao4814]

Conventionally, all acetals and ketals are called as acetals right now

[@doomedfleur12974]

@@taylorteehungpiao4814 dude thank you

[@vlvt-things]

5:43 why didn't you use the water to deprotonate turning it into h3o+, is this feasible in this type of reaction?

[@syedashobnam2573]

5:21 why do we need to form the carbonyl again, why can't we just react it with CH3-OH and the OH2 leaves?

[@potumnn]

9:37 could the acid remove the alcohol, leaving water, instead of remove the protecting group?

[@limmuquan4796]

You would get an unstable primary carbocation, so I don't think that would happen

[@sidharthapaul7316]

I think after the removal of H2O from the oxonium ion so formed, O from the initial ring coordinates lone pair to the 1° carbocation then forming a six membered ring. But for that 1° carbocation needs to be formed and the product I said has peroxy linkage which is very unstable.

[@darklight1388]

hi do you mind putting your carbohydrate video back up ? I was watching it and now it says its deleted.

[@yassineagguinechannel_1108]

Hi, Please can you tell the programm do you use for drawing the molecules and chemistry reactions .. thank you so much in advance

[@AdityaSharma-qb5qp]

bruh that stuff could be literally done on mspaint

[@cuteangle9540]

Ma'am u r great ❤❤

[@samanthalouis7814]

Can someone please help me? If I were to get the cyclic acetal structure formed after I did the protection group reaction, what would KMnO4 do to the cyclic acetal? Will it break it to for two carboxylic acids or not react with the cyclic acetal group?

[@GrowUpclubwithHiba]

So helpful, thank you

[@오경호-d3d]

It's there a protecting group site?

[@jesusmrosario-claudio4104]

Thank you once again.

[@nancygold6792]

To be honest, you were only saying what you were drawing, nothing was really explained to my understanding. I prefer other of your videos to this.

[@julienalexander6113]

Man, I don't know how you do this but damn...smh. Thank you

[@abouddrogo2504]

Youhave all my support ...you are the best☺

[@ekantoro9013]

wow thanks for the video

[@aviralagarwal9700]

lol the same question from 7:24 came in my test

[@sharonangarita8794]

At 1:40, isn't it Ketal instead of Acetal? bc your staring product is a cyclic ketone?

[@isaacreasmochia3240]

It is a Ketal. May be he thought the structure was an aldehyde

[@vladys5238]

Good video

[@yasminekassim3860]

Thank you!!!

[@mohammedalbatatea6489]

Good man

[@baburali8230]

Why is acetone not good at protecting a 1,3-diol but is good at protecting a 1,2-diol?

[@rutilantly4572]

Idk man

[@rutilantly4572]

It is what it is I guess

[@juststudy9989]

Nice

[@orangefantasy5320]

🥰

[@Dogasanatseyahat]

still useful but you were really better than this. too fast!!!
