An organic compound having molecular formula C ₂ H ₆ O under goes oxidation with K ₂ Cr ₂ O ₇ / H ₂ SO ₄ to produce X which contains 40 % carbon, 6.7 % hydrogen and 53.3 % oxygen. The molecular formula of the compound X is

Options

  1. ACH ₂ O
  2. BC ₂ H ₄ O ₂
  3. CC ₂ H ₄ O
  4. DC ₂ H ₆ O ₂

Correct answer

B. C ₂ H ₄ O ₂

Step-by-step solution

C ₂ H ₅ OH - K ₂ C ₂ O ₇ / H ₂ SO ₄ CH ₃ COOH % C = 24 60 100=40 %, % H = 4 60 100=6.7 %, % O = 32 60 100=53.3 %
