Question

The number of hyperconjugation structures involved to stabilize carbocation formed in the below reaction is _______

Hint:

Hyperconjugation involves the delocalization of electrons from adjacent C-H or C-C bonds to stabilize carbocations.

Answer 1

Correct Answer: 7

In the given reaction, the carbocation formed after the removal of \( H^+ \) can undergo several hyperconjugation structures. We see that the carbocation can shift, and the hyperconjugation structures involve the bonding electrons of the adjacent C-H bonds.
After shifting, the carbocation is stabilized by the hyperconjugation effect, and counting all the hyperconjugation structures (including the shift), there are 7 such structures.
Thus, the correct number of hyperconjugation structures is 7. Therefore, the correct answer is (2).
