Question

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)

Options

• 75

• 69

• 56

• 30

Answer 1

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 69.

Explanation:

Molecular formula of product 'P' = C₇H₆O₂

So, mass % of C in 'P' = `(12 xx 7)/(84 + 6 + 32) xx 100 = 68.85% ~~ 69%`
