Per NCERT §8.7.8, the ELECTROMERIC EFFECT (E) is best described as which kind of effect?
APermanent σ-polarisation in the chain
Bσ-electron delocalisation into C-H
CTemporary π-shift on demand of reagent
DThrough-space dipole-dipole effect
Answer & Solution
Correct answer: C. Temporary π-shift on demand of reagent
NCERT §8.7.8: E-effect is a temporary complete transfer of π-electrons on demand by a reagent; gone once reagent leaves.
