A hydrocarbon contains `10.5 gm` carbon and `1 gm` hydrogen. Its `2.4 gm` has `1 L` volume at `1 atm` and `127^(@)C`, hydrocarbon is

A

`C_(6)H_(7)`

B

`C_(6)H_(8)`

C

`C_(5)H_(6)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
`C = 10.5 gm = (10.5)/(12) mol = 0.87 mol`
`H = 1 gm = (1)/(1) = 1mol`
`:. (C_(0.87)H_(1))_(7) = C_(6.09)H_(7) = C_(6)H_(7)`
`PV = nRT`, `PV = (w)/(m)RT`
`1 xx 1 = (2.4)/(m) xx 0.082 xx 400`
`m = 2.4 xx 0.082 xx 400 = 78.42 = 79`.
