Some Basic Principles Of Organic Chemistry Question 104

Question: An organic compound has an empirical formula CH2O , its vapour density is 45. The molecular formula of the compounds is [DCE 2004]

Options:

A) CH2O

B) C2H5O

C) C2H2O

D) C3H6O3

Show Answer

Answer:

Correct Answer: D

Solution:

Mol.

wt = 2 × Vap.

Density =2×45=90 Empirical formula weight =12+2+16=30

,n=mol.wt.empirical formula wt.

=9030=3
Molecular formula of the compounds =(CH2O)3

=C3H6O3
