The reaction of phenol with benzoyl chloride to give phenyl benzoate is known as

The major product of the acetylation of salicylic acid with $Ac_2O/H^+$ followed by heating with anhydrous $AlCl_3$ is

Compound $A$ $(C_7H_8O)$ is insoluble in water,dilute $HCl$,and aqueous $NaHCO_3$,but it dissolves in dilute $NaOH$. When $A$ is treated with $Br_2$ water,it is converted into a compound $C_7H_5OBr_3$ rapidly. The structure of $A$ is

In the Liebermann’s nitroso reaction,the changes in the colour of phenol occur as:

The major product in the following reaction is:

The ionisation constant of phenol is higher than that of ethanol because
