Question

An organic compound (A) of molecular formula C₂H₃OCI on reaction with pd and BaSO₄ gives (B) of formula C₂H₄O. (B) on reaction with LiAIH₄ gives (C) of formula C₂H₆O. (B) on reaction with 12 and NaOH gives (D) of formula CH₂ONa and iodoform. identify A,B,C,D and explain the reactions involved.

Answer 1

1. From the molecular formula (A) is identified as CH₃COCl (Acetyl chloride) 

2. Acetyl chloride on treatment with Pd and BaSO₄ gives acetaldehyde CH₃CHO as (B)

3. Acetaldehyde on reaction with LiAIH₄ gives ethyl alcohol as (C)

4. Acetaldehyde when treated with I and NaOH gives sodium formate (D) and iodoform CHI as products.
