) with general formula 
or an alkyne 
general formula 
Our of the list of the hydrocarbons given : 
(Propene) is an alkene
with bond. It corresponds to general formula 
(Ethyne) is an
alkyne with 
bond., it corresponds to general formula 
Both these hydrocarbons take part in addition reaction. For example, they react with hydrogen upon heating to 473 K in the presence of nickel catalyst to form corresponding alkanes.
