Which of the following hydrocarbons is the most reactive towards addition of H ₂ SO ₄ ?

Options

  1. AEthene
  2. BPropylene
  3. C3-methyl but-1-ene
  4. D1-butene

Correct answer

C. 3-methyl but-1-ene

Step-by-step solution

As -bond is more activated, the addition of H ₂ SO ₄ is carried out fastly. In the given compound, 3-methyl but-1-ene. Undergoes rapid addition, because -bond is activated by hyperconjugation and after addition the most stable 3^ -carbocation is formed.
