Which compound from following has highest boiling point?
  1. $\mathrm{n}^{-}-\mathrm{C}_4 \mathrm{H}_9 \mathrm{OH}$
  2. $\left(\mathrm{CH}_3\right)_3 \mathrm{C}-\mathrm{NH}_2$
  3. $\quad \mathrm{C}_2 \mathrm{H}_5 \mathrm{~N}\left(\mathrm{CH}_3\right)_2$
  4. $\mathrm{C}_2 \mathrm{H}_5 \mathrm{COOH}$

Solution

Intermolecular hydrogen bonding is maximum in carboxylic acids. Hence, among the given compounds, $\mathrm{C}_2 \mathrm{H}_5 \mathrm{COOH}$ has the highest boiling point.
