उत्तर
Addition Reaction : The reactions in which molecules of the attacking reagent add across the double or triple bond of an unsaturated compound to yield saturated compound.
Ethene is a reactive compound due to presence of double bond. hence undergo addition reactions.
Two examples:
(i) Addition of hydrozen : \[\ce{CH2 = CH2 + H2 ->[ni][300°C] Ch3 - CH3}\]
(ii) Addition of halogens: \[\ce{Ch2 = CH2 + Br -> CH2Br - Ch2Br}\]
