A solution of phenol in chloroform when treated with aqueous NaOH gives compound P as a major product.

Now, 

The mass percentage of carbon in (P)

= (total mass of C in P) /(total mass of P) X 100

 

Total mass of P = The molecular weight of C7H6O2  =  122

Total mass of C in P = 12 X 7 

,So,

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

Ans = 69
