Question

Two organic compounds x and y containing Carbon and Hydrogen only have vapor densities 13 and 39 respectively. State the molecular formula of x and y. C=12, H=1

Answer 1

As Molecular Mass = 2 multiply by Vapour density...

Molecular mass of x will be 26
Molecular mass of Y will be 78

Molecular formula for x is C2H2
Molecular formula of Y is C6H6

Hope you get your answe.
