Explanation:
- Aniline is normally used to form a coloured Schiff's base with an aldehyde. - Carbylamine reaction mechanism includes the addition of amine to the intermediated created from the dehydrohalogenation of chloroform. The carbylamines reaction is also known as Hoffmann isocynide synthesis. - When active hydrogen-containing compounds reacts with benzyl chloride and aqueous sodium hydroxide then amide is formed.

Secondary nitroalkanes can be converted into ketones by using $Y$. Identify the $Y$ from the following
1 Aqueous $\mathrm{HCl}$
2 Aqueous $\mathrm{NaOH}$
3 $\mathrm{KMnO}_{4}$
4 $\mathrm{CO}$
Explanation:
Secondary nitro alkanes upon hydrolysis with boiling $\mathrm{HCl}$ (aqueous) gives a ketone \& nitrous oxide.

Aniline is prepared in presence of $\mathrm{Fe} / \mathrm{HCl}$ from
1 benzene
2 nitrobenzene
3 dinitrobenzene
4 None of these
Explanation:
Aniline is prepared by the reduction of nitrobenzene in acidic medium. Mechanism $3 \mathrm{Fe}+6 \mathrm{HCl} \rightarrow 3 \mathrm{FeCl}_{2}+6 \mathrm{H}$ $\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{NO}_{2}+6 \mathrm{H} \rightarrow \mathrm{C}_{6} \mathrm{H}_{5} \mathrm{NH}_{2}+2 \mathrm{H}_{2} \mathrm{O}$ $\mathrm{FeCl}_{2}+2 \mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{Fe}(\mathrm{OH})_{2}+2 \mathrm{HCl}$ So, $\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{NO}_{2}+2 \mathrm{Fe}(\mathrm{OH})_{2}+4 \mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{C}_{6} \mathrm{H}_{5} \mathrm{NH}_{2} \mathrm{Fe}(\mathrm{OH})_{3}$
