Question

Ail organic compound has 42.1% carbon, 6.4% hydrogen and remainder is oxygen. If its molecular weight is 342, then its molecular formula is :

• A. \(C_{11}H_{18}O_{12}\)
• B. \(C_{12}H_{20}O_{12}\)
• C. \(C_{14}H_{20}O_{10}\)
• D. \(C_{12}H_{22}O_{11}\)

Answer 1

The Correct Option is D

Only C₁₂H₂₂O₁₁ has 42.1% carbon, 6.4% hydrogen, and 51.5% oxygen.
Thus the correct answer is Option 4.
