Why does benzoic acid not participate in friedel-craft reaction..?
✋
koi dhakka mukki nahi karega ek ek kar ke answer do ✋

Answer:
The -COOH gr (carboxylic group) attached to the benzene ring is electron withdrawing and ring deactivating. Benzoic acid does not undergo Friedel-Craft Alkylation Reaction. The reagent then undergoes polymerization, degradation and is not available for the reaction with the substrates of low reactivity.
hope it help you. ...
thank you ....
Answer:
»Benzoic acid does not undergo Friedel-Crafts reaction due to deactivation of the benzene ring by the electron withdrawing effect of -COOH group.
»The reaction is electrophilic aromatic substitution reaction. Aromatic nucleus acts as nucleophile. Any group that decreases the electron density of aromatic nucleus, will deactivate the ring towards electrophilic aromatic substitution.
