$p$-Hydroxybenzophenone upon reaction with bromine in carbon tetrachloride gives

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 $....$

Suppose the following reaction:
$CH_3-CH_2-OH$ $\xrightarrow{Cl_2/NaOH} A$ $\xrightarrow{\text{Phenol}/OH^-} \text{Major Product}$
The structure of the Major Product will be:

The reaction of concentrated $HNO_3$ with phenol forms:

Sodium phenoxide reacts with $CO_2$ at $400\,K$ and $4-7\,atm$ pressure to give

Which of the following compounds will most easily be attacked by an electrophile?
