A solution of phenol in chloroform when treated
with aqueous NaOH 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)
(Atomic mass : C = 12; H = 1; O = 16)
Correct Answer: 69
Explanation:
mass of Salicylaldehyde = 12 × 7 + 6 × 1 + 16 × 2 = 122
mass of carbon = 12 × 7 = 84
$ \therefore $ mass % of C in P = ${{84} \over {122}}$ $ \times $ 100
= 68.85 % $ \simeq $ 69 %
