Options
- A. A, C and D only
- B. A and B Only
- C. A and C Only
- D. B and C Only
Answer
C. A and C Only
Step-by-step solution
A: Cation at C_1. -carbons are Methyl (3H), C_2 (1H), C_6 (2H). Total = 6. B: Cation at C_1. -carbons are Methyl (3H), C_2 (2H), C_6 (2H). Total = 7. C: Cation at C_1. -carbons are Methyl (3H), C_2 (1H), C_6 (2H). Total = 6. D: Cation at C_1. -carbons are Ethyl group's CH_2 (2H), C_2 (1H), C_6 (2H). Total = 5. A and C both have 6 -hydrogens, thus they have the same number of hyperconjugation structures.
