Solution

The correct option is A An aryl halide with an $- N O_{2}$ and a strong nucleophile.

An aryl halide with $- N O_{2}$ substituents are highly activated for aromatic nucleophilic substitution reaction.

Which of the following statement is true regarding esterification of a carboxylic with an alcohol ?

(i) It is carried out in presence of a strong acid which acts as a catalyst.

(ii) The strong acid makes the carbonyl carbon more electrophilic, and hence causes the alcohol, a strong nucleophile to attack on the carbonyl carbon.

(iii) The strong acid makes the carbonyl group more electrophilic which is thus attacked easily by an alcohol. a weak nucleophile.

(iv) Esterification can be done even in absence of a strong, acid.

Q. An aryl halide gives nucleophilic substitution reaction when:

Q. An acidic salt is formed by the reaction between a strong acid and a strong base.

Q. Assertion :
