Assertion (A) : Boiling point of $\displaystyle \left(\mathrm{C}_{2} \mathrm{H}_{5}\right)_{2} \mathrm{NH}$ is lower than that of $\displaystyle \mathrm{n}-\mathrm{C}_{4} \mathrm{H}_{9} \mathrm{NH}_{2}$. Reason (R) : Hydrogen bonding is much more extensive in $\displaystyle \mathrm{n}-\mathrm{C}_{4} \mathrm{H}_{9} \mathrm{NH}_{2}$ as compared to $\displaystyle \left(\mathrm{C}_{2} \mathrm{H}_{5}\right)_{2} \mathrm{NH}$.
