Options

  1. AHydrogen atom from α-carbon and a halogen atom from β-carbon
  2. BHydrogen atom from β-carbon and a halogen atom from α-carbon
  3. CHydrogen atom from α-carbon and a carbon atom from β-carbon
  4. DHydrogen atom from β-carbon and a carbon atom from α-carbon

Correct answer

B. Hydrogen atom from β-carbon and a halogen atom from α-carbon

Step-by-step solution

In β-elimination, a hydrogen atom is eliminated from the β-carbon, and a halogen atom is eliminated from the α-carbon.
