Empirical formula of a compound is CH(2)...

Empirical formula of a compound is `CH_(2)O` and its molecular mass is 90. The molecular formula of the compound is

A

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

B

`C_2H_4O_2`

C

`C_6H_(12)O_(6)`

D

`CH_2O`

Text Solution

Verified by Experts

The correct Answer is:
A
E.F weight `=1.2+1xx2+16=30`
Molecular mass=90
`therefore n=("Molecular mass")/("E.F. mass")=90/30=3`
Hence M.F `=3xxCH_(2)O=C_(3)H_(6)O_(3)`
