A compound has an empirical formula C(2)...

A compound has an empirical formula `C_(2)H_(4)O`. An independent analysis gave a value of 132.16 for its molecular mass. What is the correct molecular formula .

A

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

B

`C_(10)H_(12)`

C

`C_(7)O_(3)`

D

`C_(6)H_(12)O_(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
Empricial formula wieght `C_(2)H_(4)O`
` = (12 xx 2 + 4+ 16) = 44`
Molecular formula ` =("mol . Wt")/("eq. formula wt") xx "Emp. Formula "`
` = (132.1)/(44) xx` Emperical formula .
` = 3 xx C_(2)H_(4)O = C_(5)H_(12)O_(5)`
