Pyrolysis of methane and ethane respectively are:
1 Exothermic & Endothermic
2 Endothermic & Exothermic
3 Both are endothermic
4 Both are exothermic
Explanation:
Pyrolysis is endothermic reaction (heating in the absence of oxygen).

Liquid hydrocarbon can be converted to a mixture of gaseous hydrocarbon by
1 Oxidation
2 Cracking
3 Hydrolysis
4 Distillation under reduced pressure
Explanation:
Cracking converts liquid hydrocarbons to gaseous hydrocarbons by cleavage of \({\text{C - C}}\) bond and \(\mathrm{C}-\mathrm{H}\) bonds.
