Aspirin is obtained by the reaction of $CH_3COCl$ with

The major product of the following reaction sequence is:
$C_6H_5OH \xrightarrow[(ii) NaOH, (iii) H^+]{(i) CHCl_3, NaOH(aq)} ?$

Reaction of phenol with $NaOH$ followed by heating with $CO_{2}$ under high pressure,and subsequent acidification gives compound $X$ as the major product,which can be purified by steam distillation. When reacted with acetic anhydride in the presence of a trace amount of conc. $H_{2}SO_{4}$,compound $X$ produces $Y$ as the major product. Compound $Y$ is $....$

Phenol reacts with bromine in carbon disulphide $(CS_2)$ at low temperature to give:
