The molecular weight of an organic compo...

The molecular weight of an organic compound is 180. Its empirical formula is `CH_(2)O`. Its molecular formula is

A

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

B

`C_(2)H_(16)O_(5)`

C

`C_(5)H_(4)O_(5)`

D

`C_(5)H_(8)O_(7)`

Text Solution

Verified by Experts

The correct Answer is:
A
The molecular mass of the given empirical formula ` (CH_(2)O)` is,
12+2+16=30
` n= ("Molecular weight")/("empirical formula weight")=180/30=6 `
Hence , molecular formula=nxxEmpiricial formula
