A compound with empirical formula XY2 has vapour density equal to its empirical formula weight its molecular formula is

A

`X_(2)Y_(4)`

B

`X_(2)Y_(2)`

C

XY

D

`X_(4)Y_(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
Molecular formula `= n xx` Empirical formula
And Molecular formula `=2 xx` Vapour density
Thus, `n xx` Empirical formula `=2 xx` Vapour density
Therefore, n=2 (Empirical formula= Vapour density)
Molecular formula `=2 xx XY_(2)= X_(2)Y_(4)`
