Identify the name of the reaction when phenol reacts with chloroform in the presence of aqueous $NaOH$.

Benzoic acid on heating with $X$ gives benzene and phenol on heating with $Y$ gives benzene. What are $X$ and $Y$ respectively?

$4.7 \text{ g}$ of phenol is heated with $Zn$ to give product $X$. If this reaction goes to $60\%$ completion, then the number of moles of compound $X$ formed will be . . . . . . $\times 10^{-2}$. (Nearest Integer) (Given molar mass in $\text{g mol}^{-1}$: $H:1, C:12, O:16$)
