The major product formed in the following reaction is :

The major product obtained on the interaction of phenol with sodium hydroxide and carbon dioxide is

Phenol is heated with a solution of a mixture of $\mathrm{KBr}$ and ${\mathrm{KBrO}}_3$. The major product obtained in the above reaction is

$\mathrm{P}-$cresol reacts with chloroform in alkaline medium to give the compound $\mathrm{A}$ which adds hydrogen cyanide to form, the compound $\mathrm{B}$. The latter on acidic hydrolysis gives chiral carboxylic acid. The structure of the carboxylic acid is
