Consider the following reaction: H2C = CH2 + HBr -> H3C - CH2Br The mechanism of reaction is:
Correct answer: B. Electrophilic addition reaction
- A. Nucleophilic addition reactions
- B. Electrophilic addition reaction
- C. Free radical substitution
- D. Nucleophilic substitution reaction
Explanation
The addition of HBr to the alkene is an electrophilic addition reaction. In this process, the π bond of the alkene acts as a nucleophile attacking the electrophile (H+ from HBr), resulting in the formation of a new carbon-carbon bond.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
