Question

The compound/s which shows hyper conjugation is / are

• A. A) Cyclohexyl carbocation with methyl substituent
• B. B) Benzene with tert-butyl group
• C. C) $(CH_3)_2 C = CH_2$
• D. D) Cyclohexylmethyl carbocation

Answer 1

Answer: (A), (B), (C), (D)

A, B, C, D

Answer 2

Hyperconjugation involves the delocalization of sigma electrons from C-H bonds into an adjacent empty p-orbital, radical, or pi system.

A) The carbocation is adjacent to C-H bonds in the methyl group and cyclohexane ring. B) The aromatic pi system is adjacent to C-H bonds of the tert-butyl group. C) The C=C double bond is adjacent to C-H bonds of the methyl groups. D) The carbocation is adjacent to a C-H bond in the cyclohexane ring. All compounds exhibit hyperconjugation.
