In the given reaction,$[X]$ will be:

Why does acetylation of $-NH_2$ group of aniline reduce its activating effect?

Assertion : Acylation of amines gives a monosubstituted product whereas alkylation of amines gives polysubstituted product.
Reason : Acyl group sterically hinders the approach of further acyl groups.

Chloropicrin is manufactured by the reaction between $Cl_2$,$NaOH$ and
