A gas with molecular formula `C_(n)H_(2n + 2)` diffuses through a porous plug at a rate `1//6th` of the rate of diffusion of hydrogen gas under similar condtition. The formula of the gas is:

Options

A. `C_(2)H_(6)`
B. `C_(10)H_(22)`
C. `C_(5)H_(12)`
D. `C_(6)H_(14)`

Answer

C

Explanation

`(r_(1))/(r_(2)) = sqrt((M_(2))/(M_(1))) , (r_(1))/(r_(1)//6) = sqrt((M_(2))/(2)) , M_(2) = 72`
`:.` The forumla of gas will be `C_(5)H_(12)`
