Which of the following hydrocarbons is the most reactive towards addition of H2SO4\mathrm{H}_2 \mathrm{SO}_4 ?Which of the following hydrocarbons is the most reactive towards addition of H_2 SO_4 ?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 π\pi-bond is more activated, the addition of H2SO4\mathrm{H}_2 \mathrm{SO}_4 is carried out fastly. In the given compound, 3-methyl but-1-ene. Undergoes rapid addition, because π\pi-bond is activated by hyperconjugation and after addition the most stable 3∘3^{\circ}-carbocation is formed. Which of the following hydrocarbons is the most reactive towards addition of H_2 SO_4 ?
