Question

An organic compound containing `C,H` and `N` have the percentage `40,13.33` and `46.67` respectively. Its empirical formula may be`:`
A. `C_(2)H_(7)N_(2)`
B. `CH_(5)N`
C. `CH_(4)N`
D. `C_(32)H_(7)N`

Answer 1

Correct Answer - C
`"Element No . of moles Simple Ratio"`
`C=40%" "40//12=3.33" "1`
`H=13.33%" "13.33//1=13.33" "4`
`N=46.67%" "7//14=3.33" "1`
Thus formula `CH_(4)N.`
