Match List-I with List-II. List-I List-II (A) The permanent effect that is weaker than the electromeric effect when they operate in opposite directions (I) Electromeric effect (B) Temporary complete transfer of electrons in the presence of an attacking reagent (II) Hyperconjugation (C) Delocalisation of electrons of a C-H bond into an adjacent system (III) Resonance effect (D) Polarity produced in a molecule by the i
Options
- A(A)-(I), (B)-(IV), (C)-(III), (D)-(II)
- B(A)-(IV), (B)-(I), (C)-(III), (D)-(II)
- C(A)-(I), (B)-(IV), (C)-(II), (D)-(III)
- D(A)-(IV), (B)-(I), (C)-(II), (D)-(III)
Correct answer
D. (A)-(IV), (B)-(I), (C)-(II), (D)-(III)
Step-by-step solution
(A) When the inductive and electromeric effects operate in opposite directions, the temporary electromeric effect predominates over the permanent inductive effect. Thus, (A) matches with Inductive effect (IV). (B) The electromeric effect involves the temporary complete transfer of shared electrons to one of the atoms joined by a multiple bond on the demand of an attacking reagent. Thus, (B) matches with Electromeric effect (I). (C) Hyperconjugation involves the delocalisation of electrons of a C-H bond of an alkyl
