Identify the correct order of boiling points of the following compounds:
$\begin{array}{lc}\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{OH} & \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{CHO} \\ 1 & 2 \\ \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{COOH} & \end{array}$
3
  1. $1>2>3$
  2. $3>1>2$
  3. $1>3>2$
  4. $3>2>1$

Solution

Due to $-\mathrm{I}$ effect of the - COOH group, H-bonds in acids are much stronger than in alcohols; while aldehydes do not exhibit $\mathrm{H}$ -bonding.
