$4$-Methylaniline on heating with alcoholic $KOH$ in the presence of chloroform gives :-

The diazonium salt of which of the following compounds will form a coloured dye on reaction with $\beta$-Naphthol in $NaOH$?

Given below are two statements: one is labelled as Assertion $(A)$ and the other is labelled as Reason $(R)$.
Assertion $(A)$: Experimental reaction of $CH_{3}Cl$ with aniline and anhydrous $AlCl_{3}$ does not give $o-$ and $p-$methylaniline.
Reason $(R)$: The $-NH_{2}$ group of aniline becomes deactivating because of salt formation with anhydrous $AlCl_{3}$ and hence yields $m-$methylaniline as the product.
In the light of the above statements,choose the most appropriate answer from the options given below.

Which of the following is hydrolysed to give a secondary amine?

When aniline is nitrated with nitrating mixture in ice-cold condition,the major product obtained is
