The major product of the following reaction is:

Give reasons:

Haloalkanes easily dissolve in organic solvents.

Give reasons:

C — Cl bond length in chlorobenzene is shorter than C — Cl bond length in chloromethane.

The correct decreasing order of densities of the following compounds is :

Give reason:

n-Butyl bromide has higher boiling point than t-Butyl bromide.

Arrange the following compounds in the decreasing order of boiling points:

$\begin{array}{c}{\mathrm{CH}}_3\mathrm{Br}\\ \left(\mathrm{i}\right)\end{array}\begin{array}{c}{\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{Br}\\ \left(\mathrm{ii}\right)\end{array}\begin{array}{c}{\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{CH}}_2\mathrm{Br}\\ \left(\mathrm{iii}\right)\end{array}\begin{array}{c}{\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{CH}}_2{\mathrm{CH}}_2\mathrm{Br}\\ \left(\mathrm{iv}\right)\end{array}$

The increasing order of the boiling points of the major products $\mathrm{A}, \mathrm{B}$ and $\mathrm{C}$ of the following reactions will be :

(a) 

(b)

(c)
