Question

An organic compound contains carbon, hydrogen and oxygen. Its elemental analysis gave`C,38.71%` and `H,9.67%`. The empirical formula of the compound would be `:`
A. `CH_(2)O`
B. `CHO`
C. `CH_(4)O`
D. `CH_(3)O`

Answer 1

Correct Answer - d
`C=(38.7)/(12)=3.22=(3.22)/(3.22)=1`
`H=(9.67)/(1)=9.67=(9.67)/(3.22)=3`
`O=(51.63)/(16)=3.22=(3.22)/(3.22)=1`
`:.` Empirical formula is `CH_(3)O`
