Embibe Experts Solutions for Chapter: Amines, Exercise 3: Exercise-3

In the reaction shown below, the major product(s) formed is/are

The alkene formed as a major product in the above elimination reaction is:

When a primary amine reacts with chloroform in ethanolic $\mathrm{KOH}$, the product is 

The compound which does not give foul smell when heated with ${\mathrm{CHCl}}_3$ and $\mathrm{KOH}$ is :-

In the following reaction, X is 

$\mathrm{X}\stackrel{\mathrm{Bromination}}{\to }\mathrm{Y}\stackrel{{\mathrm{NaNO}}_2/\mathrm{HCl}}{\to }\mathrm{Z}\underset{{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}}{\overset{\mathrm{Boiling}}{\to }}\mathrm{Tribromobenzene}$

There is a solution of $\mathrm{p}$-hydroxy benzoic acid and $\mathrm{p}$-amino benzoic acid. Discuss one method by which we can separate them. Also write the confirmatory tests of functional groups.

Statement-1: Aniline on reaction with ${\mathrm{NaNO}}_2/\mathrm{HCl}$ at $0 °\mathrm{C}$ followed by coupling with $\mathrm{\beta }$-naphthol gives a dark blue precipitate.

Statement-2 : The colour of the compound formed in the reaction of aniline with ${\mathrm{NaNO}}_2/\mathrm{HCl}$ at $0 °\mathrm{C}$ followed by coupling with $\mathrm{\beta }$-naphthol is due to the extended conjugation.
