[6/12, 2:06 PM] Rakesh Biswas New: She has to share questions and we can try to solve them together

[6/12, 3:32 PM] Rakesh Biswas New: @⁨Bibek⁩ is a well established chemistry teacher who is willing to help

[6/12, 3:36 PM] +91 97349 03477: Thank you very much 🙏

[6/12, 3:53 PM] Bibek: https://chemistry.stackexchange.com/questions/173262/reaction-of-methyl-triphenylbenzoate-with-concentrated-sulphuric-acid

Ekhane answer ta dewa ache.

[6/12, 3:55 PM] Bibek: Aami JU er entrance test er question paper pathachi.

Eto hard question hoi na.

Basic concepts er theke hoi.

[6/12, 4:21 PM] +91 97349 03477: Can you please send previous years question papers @⁨Bibek⁩

[6/12, 4:22 PM] Bibek: NEET pattern question hoy.

Organic name reaction

( Aldol, cannizaro,pinacol, gattarman, sandmayer,arnd esterd, Hans dekar,estarification,wittig,

Schimen,Grignard, Williamson,benzoin,diazonium salt,mulikan burker,

Tishchenko etc are important)

R/S Nomenclature,

Sn1/Sn2 reaction( feasibility order),chiral carbon, enantiomer, diastereomer, nucleophile, electrophile, carbonation/ anion stability order, resonance, hyperconjugation,IUPAC name( both organic or inorganic compounds)

Reaction conversion ( like Acitic acid to lactic acid )

[6/12, 4:24 PM] Bibek: Ok,I'm trying

[6/13, 6:04 PM] +91 97349 03477: Can you please explain the reason behind this acidic strength order? @⁨Bibek⁩

[6/13, 8:39 PM] +91 90001 66698: I'd say the answer is 3>1>2,but not an option.

@⁨Rakesh Biswas New⁩

[6/13, 9:41 PM] Rakesh Biswas New: 👆@⁨Bibek⁩

[6/13, 10:13 PM] +91 97349 03477: Thank you very much @⁨Bibek⁩

[6/13, 10:16 PM] +91 90001 66698: This explanation of 1>2>3 is based on electronegativity and inductive effect on acidity.

My explanation is based on conjugate base stability.

Compound 3 can spread negative charge over 3 oxygen atoms,making it very stable compared to other two

@⁨Rakesh Biswas New⁩ how do we look at this?

[6/13, 10:21 PM] +91 90001 66698: Question asks regarding 'acidic strength'.

And we can look at it like this

Concept 1-electronegativity is directly related to polarity of OH bond.

Inductive effect tells how electron withdrawing groups reduce/weaken acidity.

Conjugate base acid principle is very well established in Biochemistry..It directly relates to energetics of acid dissociation reaction and curve..

So depends on how we see it and what we weigh more(in ANN terms).

For exams,maybe what previous year answers tells?

For actually understanding concept,maybe different?

@⁨Rakesh Biswas New⁩

@⁨Bibek⁩

[6/13, 10:31 PM] +91 90001 66698: @⁨Rakesh Biswas New⁩ so the answer may different for same question based on application part and the application part for most of the above questions in this and other group is to clear exams?

[6/13, 11:12 PM] Bibek: In 2,

Due to the +R effect of OCH3 group, the OH bond strength increases,H+ ions cannot be easily freed

[6/13, 11:13 PM] +91 90001 66698: That's an amazing way to look at it

[6/15, 10:28 AM] +91 97349 03477: Sir good morning

Can you please make 50 marks question paper for 43FGAD 's daughter 🙏 @⁨Bibek⁩
