Question

Arrange the following compounds in the increasing order of their boiling points:
$\underset{I}{C{H}_{3}C{H}_{2}CHO}$ $\underset{II}{C{H}_{3}C{H}_{2}C{H}_{2}OH}$

$\underset{III}{(C{H}_3{)}_{3}C{O}^{-}{K}^{+}}$ $\underset{IV}{C_2{H}_{5}O{C}_2{H}_5}$

Answer 1

Boiling point $\alpha$ Intermolecular force of atteraction
$\underset{\text{(Ionic Forces)}}{(C{H}_3{)}_{3}CO-K^{+}}>\underset{\text{(Hydrogen bonding)}}{C{H}_{3}C{H}_{2}C{H}_{2}C{H}_{2}OH}>\underset{\text{Strong Dipole- Dipole forces}}{C{H}_{3}C{H}_{2}C{H}_{2}CHO}>\underset{\text{Weak Dipole-Dipole Forces}}{C_2{H}_{5}O{C}_2{H}_5}$
