Question

Find which of the following compound can have mass ratio of C:H:O as 6:1:24

• A. HO-(C=O)-OH
• B. HO-(C=O)-H
• C. H-(C=O)-OH
• D. H₃CO-(C=O)-H

Hint:

Always convert mass ratio into mole ratio to identify compounds.

Answer 1

The Correct Option is A

Step 1: Convert mass ratio to mole ratio: C: (6)/(12)=0.5, H: (1)/(1)=1, O: (24)/(16)=1.5 Step 2: Simplify: 0.5:1:1.5 = 1:2:3 Step 3: Empirical formula: CH₂O₃ Step 4: This corresponds to carbonic acid: HO-(C=O)-OH
