Solution
The correct option is B False
The reaction in which an atom or a group in a compound is replaced by another atom or a group is called a substitution reaction. The reaction in which atoms combine with unsaturated carbon compounds to form saturated carbon compounds is called addition reaction. During the formation of ethene, the triple bond between carbon atoms is breaking and the hydrogen atom is substituting there forming an alkene from an alkyne. Therefore the given reaction is an addition reaction and not a substitution reaction.
