The empricial formula of a compound is `CH_(2)O`. Its molecular weight is 120. The molecular formula of the compound is

A

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

B

`C_(4)H_(8)O_(4)`

C

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

D

`C_(6)H_(12)O_(6)`

Verified by Experts

The correct Answer is:

B

Empirical formula weight = 30
`n=(120)/(30)=4`
Molecular formula = `(CH_(2)O)_(4)=C_(4)H_(8)O_(4)`
