Question

An organic compound (A) of molecular formula C₇H₈ reacts with CI₂ in the presence of ho light gives (B) of formula C₇H₆C₁₂ . (B) on hydrolysis at 373 k gives (C) of formula C₇H₆O. (C) on treatment with 50% NaOH gives (D) and (E). Identify A,B,C,D,E and explain the reactions involved.

Answer 1

1. From the molecular formula (A) is identified as Toluene. ToÍuene reacts with Cl₂ in the presence of light gives Benzal chloride as (B)

2. Benzal chloride on hydrolysis at 373 k gives Benzaldehyde as (C)

3. Benzaldehyde when warmed with dilute NaOH undergoes cannizaro reaction to give Benzyl alcohol (D) and sodium benzoate (E)
