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.
