One mole of a hydrocarbon contains 36g of carbon and its vapour density is 20. The structure of the hydrocarbon is

Answer Details

2VD = Rmm VD = Vapour density; Rmm - Relative
2 * 20 = 40 Molecular mass
Mole of carbon = 36/12 = 3
Mole of H2 = 40 - 36 = 4
The compound contains 3 mole of carbon and 4 hydrogen
