Per NCERT §8.7.9, HYPERCONJUGATION involves the delocalisation of which type of electrons?
AInner-shell core electrons
Bσ-electrons of alkyl C-H bonds
Cπ-electrons of C=O carbonyl
DLone pairs on oxygen atoms
Answer & Solution
Correct answer: B. σ-electrons of alkyl C-H bonds
NCERT §8.7.9: hyperconjugation = delocalisation of C-H σ-electrons of an alkyl group into an adjacent empty p or π orbital.
