Out of the compounds below,the vapour pressure of $(B)$ at a particular temperature is:

Out of the two compounds $A$ ($p$-nitrophenol) and $B$ ($o$-nitrophenol) shown below,the vapour pressure of $B$ at a particular temperature is expected to be:

$4.7 \text{ g}$ 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 $\text{g mol}^{-1}$: $H:1, C:12, O:16$)
