Question

Benzoic acid does not undergo friedel craft reaction why

Answer 1

Answer:

because it do not have alpha hydrogen atom which is necessary for friedel craft reaction

Explanation:

Answer 2

Answer -

It could be that −COOH group is electron withdrawing hence there is an increased electron density in −COOH group due to -R resonating effect of electron from benzene ring.

It could be that −COOH group is electron withdrawing hence there is an increased electron density in −COOH group due to -R resonating effect of electron from benzene ring.Since friedel craft catalyst is a Lewis acid (electron deficient) the catalyst (anhydrous AlCl3) reacts with electron rich COOH group of benzoic acid and gets bonded.
