The empirical formula of an organic comp...

The empirical formula of an organic compound is `CH_(2)O`. If its vapour density is `30`, the molecular formula of the compound is :

`CH_(2)O`

`C_(2)H_(4)O_(2)`

`C_(3)H_(6)O_(3)`

all the above

Text Solution

Verified by Experts

The correct Answer is:

Empirical formula mass `=1xx12+2xx1+1xx16=30`
Molecular formula mass `=30xx2=60`
`n=(60)/(30)=2`
Molecular formula `=(CH_(2)O)=C_(2)H_(4)O_(2)`
