Question

If empirical formula of an organic compound is CH2O then its molecular formula can be:
a) C2H2O2 b) C2H4O c) C3H6O d) C6H12O6

Answer 1

Answer:

Correct option is

D

C3H6O3

The empirical formula is CH2O. Therefore, the empirical weight = 30 g.

Given, the molecular weight = 2×V.D = 2×45=90 g.

x=Empirical weightMolecular weight=3090=3

Molecular Formula=(Empirical Formula)x

∴Molecular Formula=(CH2O)3=C3H6O3

Answer 2

Answer:

If empirical formula of an organic compound is CH2O then its molecular formula can be:

d) C6H12O6
