Find the number of hyperconjugation structures in the isopropyl carbocation.
Options
- A3
- B6
- C9
- D12
Correct answer
B. 6
Step-by-step solution
The structure of the isopropyl carbocation is (CH₃)₂CH^+ . The carbon atom bearing the positive charge is attached to two methyl groups. The number of -hydrogens is the total number of hydrogen atoms attached to the -carbons. Here, there are two -carbons, each having 3 hydrogen atoms. Thus, the total number of -hydrogens is 3 + 3 = 6 . The number of hyperconjugation structures is equal to the number of -hydrogens. Therefore, the number of hyperconjugation structures is 6 . Answer: 6
