Question

Give an example (with equation) of an addition reaction of an alkene.

Answer 1

Ethene reacts with hydrogen when heated in the presence of a nickel catalyst to form ethane.

\[\ce{\underset{(Unsaturated)}{\underset{Ethene}{CH2 = CH2}} + \underset{Hydrogen}{H2} ->[Ni catalyst][Heat] \underset{(Saturated)}{\underset{Ethane}{CH3 - CH3}}}\]
