An organic compound (A) having molecular formula `C_2 HCl_3 O` reduces Fehling's solution and on oxidation gives a monocarboxylic acid (B) with molecular formula `C_2 HCl_3 O_2`. Upon distillation with sodalime, (B) gives a sweet smelling liquid (C) containing 89.12% chlorine. (C) can also be obtained by heating (A) with alkali. Identity (A), (B) and (C) and explain the reactions involved.

Explanation

To solve the problem, we need to identify the organic compounds (A), (B), and (C) based on the information provided and the reactions involved.

### Step 1: Identify Compound A
The molecular formula of compound (A) is given as C₂HCl₃O. It is mentioned that (A) reduces Fehling's solution, which indicates the presence of an aldehyde group. The only structure that fits this description is chloral, which has the formula CCl₃CHO.

**Compound A: CCl₃CHO (Chloral)**

### Step 2: Oxidation of Compound A to form Compound B
