When phenol is treated with bromine water,the white precipitate formed is

The major product formed in the following reaction is:

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 $g \ mol^{-1}$: $H:1, C:12, N:14, O:16$)

Explain why nucleophilic substitution reactions are not very common in phenol.

The major product of the following reaction is:

The major product in the following reaction is:
