Vedclass · Answer

(A) The reaction of chloral $(CCl_3CHO)$ with chlorobenzene in the presence of concentrated $H_2SO_4$ produces $DDT$ ($p,p'$-dichlorodiphenyltrichloroethane).This reaction involves the condensation of two molecules of chlorobenzene with one molecule of chloral,resulting in the elimination of a water molecule.The mechanism is an electrophilic aromatic substitution where the protonated chloral acts as an electrophile attacking the chlorobenzene ring.Since both the assertion (that chloral reacts with chlorobenzene to form $DDT$) and the reason (that it is an electrophilic substitution reaction) are correct,and the reason correctly explains the mechanism of the reaction,option $A$ is the correct answer.

Assertion : Chloral reacts with chlorobenzene to form $DDT$.
Reason : It is an electrophilic substitution reaction.
