The reaction of halogens with alkanes in the presence of sunlight is an example of
oxidation reaction
addition reaction
hydrogenation reaction
substitution reaction
Explanation
Alkanes undergoes substitution reaction and it is an example of halogenation substitution reaction.
Reaction of halogen with alkane in the presence of sunlight (ultraviolet) is termed halogenation. Halogenation is an example of substitution reaction. In addition, alkanes only undergo substitution reaction but not addition reaction.
