M K Verma Solutions for Chapter: Organic Compounds Containing Nitrogen, Exercise 1: TOPICWISE QUESTIONS

Stable diazonium salts are products of a reaction between nitrous acid and:

${\mathrm{RNH}}_2$ reacts with ${\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{SO}}_2\mathrm{Cl}$ in aqueous $\mathrm{KOH}$ to give a clear solution. On acidification, a precipitate is obtained which is due to the formation of

An optically inactive amine $\left(\mathrm{A}\right), {\mathrm{C}}_4{\mathrm{H}}_{11}\mathrm{N}$ on treatment with ${\mathrm{HNO}}_2$ gives an alcohol $\left(\mathrm{B}\right)$. The compound $\left(\mathrm{B}\right)$ on heating with concentrated ${\mathrm{H}}_2{\mathrm{SO}}_4$ at $453 \mathrm{K}$ gives an alkene $\left(\mathrm{C}\right).$ $\left(\mathrm{C}\right)$on treatment with $\mathrm{HBr}$ gives an optically active compound $\left(\mathrm{D}\right)$ having molecular formula ${\mathrm{C}}_4{\mathrm{H}}_9\mathrm{Br}.$ Identify $\left(\mathrm{A}\right)$.

Which of the following will evolve ${\mathrm{N}}_2$ gas on reaction with ${\mathrm{HNO}}_2$?
(a) Acetamide
(b) Isopropyl amine
(c) Ethylmethylamine
(d) Aniline
(e) $\mathrm{n}-$propylamine

In the above reaction sequence, $\mathrm{C}$ is:

The product $\mathrm{F}$ is

Arrange the following amides according to their relative reactivity when treated with ${\mathrm{Br}}_2$ in excess of strong base $\left(\mathrm{KOH}\right)$ ?

Which of the following is correct with respect to a primary amine?
(a) It is an organic compound with two $-\mathrm{NH}$ groups and no carbon atom.
(b) It is a compound with two carbon atoms and an $-{\mathrm{NH}}_2$ group.
(c) It is a compound with an $-{\mathrm{NH}}_2$ group on the carbon atom at the second position.
(d) It is a compound in which, two of the hydrogen atoms of ${\mathrm{NH}}_3$ has been replaced by an alkyl group.
(e) It is a compound in which, all of the hydrogen atoms of ${\mathrm{NH}}_3$ has been replaced by alkyl groups.
