Per NCERT §8.7.5, the INDUCTIVE EFFECT in a chain of σ-bonds is best described as which?
APermanent σ-bond polarisation by EN atom
BResonance across π-bonds in system
CTemporary π-electron shift on demand
DHyperconjugation through C-H bonds
Answer & Solution
Correct answer: A. Permanent σ-bond polarisation by EN atom
NCERT §8.7.5: inductive = permanent polarisation of σ-bonds by an electronegative substituent. Decreases with distance.
