Electrophilic substitution in benzoic acid takes place at meta position why ?

(a) How will you convert (i) Benzene to acetophenone (ii) Propanone to 2-Methylpropan-2-ol (b) Give reasons : (i) Electrophilic substitution in benzoic acid takes place at meta position. (ii) Carboxlic acids are higher boiling liquids than aldehydes,, ketones and alchols of comparable molecular masses. (iii) Propanal is more reactive than propanone in nucleophilic addition reactions.

Electrophilic subsitution reaction in phenol take place at :

Electrophilic substitution in case of aromatic amines takes place more readily than in benzene.

The substitution will mainly take place at position :

Electrophilic aromatic substitution is difficult in

Assertion : Aromatic aldehydes and ketones undergo electrophilic substitution reaction at metaposition. Reason : Carbonyl group activates the ring towards electrophilic substitution reactions.

In electrophilic substitution reactions of haloarenes, halogen atom is

Assertion: In monohaloarenes, further electrophilic substitution occurs at ortho and para position Reason: Halogen atom is a ring deactivator

Explain why are electrophilic substitution reactions the most characteristic reactions of benzene?
