Q. A solution of phenol in chloroform when treated with aqueous $N a O H$ gives compound $P$ as a major product. The mass percentage of carbon in $P$ is ____.(to the nearest integer) (Atomic mass : $C = 12; H = 1; O = 16)$

Molecular weight of $C_{7} H_{6} O_{2} = 122$

$% C = \frac{12 \times 7 \times 100}{122} = 68.85 \approx 69$
