Chemistry Organic Chemistry - Some Basic Principles and Techniques MHT CET 2026

Which of the following statements are TRUE?

(I) Inductive effect operates through the sigma bond

(II) Resonance effect operates through the pi bond

(III) Inductive effects operate through the pi bond

(IV) Resonance effect operates through the sigma bond

(A)(I) and (II)Correct
(B)(II) and (III)
(C)(III) and (IV)
(D)(I) and (IV)

Answer: (A)

Solution

The inductive effect is the permanent polarisation of a sigma bond caused by an electronegative atom/group and is transmitted along the chain of sigma bonds, so statement (I) is true and (III) is false. The resonance (mesomeric) effect arises from delocalisation of pi
