Asked in KMU MDCAT 2023 2023Moderate

Greater number of Alkyl groups on substrate favours:

Correct answer: B. Elimination reaction

  • A. Substrate reaction
  • B. Elimination reaction
  • C. Oxidation reaction
  • D. Free radical reaction

Explanation

A greater number of alkyl groups on a substrate favors elimination reactions because it leads to the formation of more stable and substituted double bonds, reduces steric hindrance, enhances hyperconjugation, and stabilizes the transition state of the elimination reaction.

About Elimination Reactions

Elimination reactions remove a leaving group and a hydrogen atom from adjacent carbon atoms to form an alkene. The topic covers dehydrohalogenation of alkyl halides, E1 and E2 mechanisms, the role of base, solvent and substrate structure, and Zaitsev orientation, which is often contrasted with substitution.
