The compound that is most difficult to protonate is

Thymol,which is primarily a derivative of phenol,is used in which of the following?

One mole of phenol is treated with dilute $HNO_3$ at $298 \ K$ to give a mixture of products. The mixture is separated by steam distillation. The steam volatile compound $(X)$ is separated. The increase in percentage of oxygen in $(X)$ with respect to phenol is . . . . . . $\times 10^{-1}$ %. (Given molar mass in $g \ mol^{-1}$: $H:1, C:12, N:14, O:16$)

When phenol reacts with ammonia in the presence of $ZnCl_2$ at $300 \ ^oC$,it gives:
