The cyclic cations having the same number of hyperconjugation are : Choose the correct answer from the options given below :

Options

  1. AA, C and D only
  2. BA and B Only
  3. CA and C Only
  4. DB and C Only

Correct answer

C. A and C Only

Step-by-step solution

A: Cation at C₁ . -carbons are Methyl (3H), C₂ (1H), C₆ (2H). Total = 6. B: Cation at C₁ . -carbons are Methyl (3H), C₂ (2H), C₆ (2H). Total = 7. C: Cation at C₁ . -carbons are Methyl (3H), C₂ (1H), C₆ (2H). Total = 6. D: Cation at C₁ . -carbons are Ethyl group's CH₂ (2H), C₂ (1H), C₆ (2H). Total = 5. A and C both have 6 -hydrogens, thus they have the same number of hyperconjugation structures.
