Per NCERT §8.7.9, in the ethyl cation (CH₃CH₂⁺), the C-H σ-electrons of which group delocalise into the empty p orbital?
AMethyl group
BPhenyl group
CCyano group
DHydroxyl group
Answer & Solution
Correct answer: A. Methyl group
NCERT §8.7.9 Fig 8.4(a): the C-H bonds of the methyl group align with the empty p orbital of the cation centre, stabilising it.
