The molecular mass of a compound having ...

The molecular mass of a compound having empirical formula `C_2H_5O` is 90. The molecualr formula of the compound is:

A

`C_6H_(15)O_3`

B

`C_4H_(10)O_2`

C

`C_2H_5O`

D

`C_3H_6O_3`

Text Solution

Verified by Experts

The correct Answer is:
B
`E.F.W.=C_2H_5O=12xx2+5xx16=45`
`n=(M.W)/(E.F.W)=(90)/(45)=2`
molecular formular `=C_4H_(10)O_2`
