Question

Benzoic acid does not give friedel craft reaction why

Answer 1

There are two Reasons.
(1)Due to deactivation of benzene ring by electron withdrawing effect of the -COOH group.
(2) The catalyst AlCl3 gets bonded to the -COOH group.

Answer 2

Hey dear,

● Benzoic acid don't undergo Friedel Craft's acylation because -
- Friedel craft reactions are favoured by ring activating groups like alkyl, halogen, etc.
- As carboxyl(-COOH) is ring deactivating group, it prevents compound from this reaction.
- Also benzoic acid reacts with AlCl3 itself to form benzoyl chloride.
- Therefore, benzoic acid don't undergo Friedel Craft's acylation.


Hope this helped you...
