Solution

The correct option is B False
Alkenes are the homologous series of unsaturated hydrocarbons. They differ from alkanes due to the presence of double bonds. Alkenes mainly undergo addition reactions.
Due to absence of unsaturation, methane doesnt give addition but due to presence of double bond ethene gives addition reaction.
