Question

Which of the following statements is INCORRECT about hyperconjugation?

Options

• Hyperconjugation is also known as no bond resonance.

• Hyperconjugation is a permanent effect which stabilizes cation.

• Greater the number of alkyl groups attached to the positively charged carbon atom, greater is the effect of hyperconjugation.

• Hyperconjugation arises due to the partial overlap of sp²−s with the empty p-orbital of adjacent positively charged carbon atom.

Answer 1

Hyperconjugation arises due to the partial overlap of sp²−s with the empty p-orbital of adjacent positively charged carbon atom.

Explanation:

The partial overlap of sp³−s (α C-H bond) with the vacant p-orbital of a nearby positively charged carbon atom causes hyperconjugation.
