Question

Which of the following will show Friedel Crafts acylation ?
A ) aniline B ) benzoate ion C ) benzoic acid D ) nitrobenzene

Answer 1

Anuiline. The reason is for Friedel Crafts acylation reaction, the electrophile is the CH₃CO⁺ which will attack the benzene nucleus if it has the negative electron density. Other options have electron withdrawing groups which will create benzene nucleus with positive electron density. Only aniline has electron releasing mesomeric effect which makes the benzene nucleus more electron denser.
