An organic compound (A) having molecular weight, 58, contained 62.06% of C and 10.35% of H and rest, oxygen (A),on reduction gave (B) which gave iodoform test.(B), on dehydration, gave an unsaturated hydrocarbon (C ) having molecular weight 42. Find (A), (B) and (C)

Explanation

To solve the problem step by step, let's break it down into manageable parts.

### Step 1: Determine the composition of compound A
Given:
- Molecular weight of A = 58 g/mol
- Percentage of Carbon (C) = 62.06%
- Percentage of Hydrogen (H) = 10.35%
- Percentage of Oxygen (O) = 100% - (62.06% + 10.35%) = 27.59%
