Let us determine with which of the listed substances the alkenes react.
1. Reaction with hydrogen. Hydrogenation reaction.
R – CH = CH2 + H2 = R – CH2 – CH3.
2. Reaction with oxygen. Combustion reaction.
2 CH2 = CH2 + O2 = 2 CH3CHO.
3. Reaction with water. Hydration reaction.
R – CH = CH2 + HOH = R – CHOH – CH3.
4. Reaction with hydrochloric acid. Hydrohalogenation reaction.
R – CH = CH2 + HCl = R – CHCl – CH3.
5. Reaction with potassium permanganate.
3CH2 = CH2 + 2KMnO4 + 4H2O = 3CH2OH – CH2OH + 2KOH + 2MnO2.
