Which among the following statements are true with respect to electronic displacement in a covalent bond?
(1) Inductive effect operates through a `pi` - bond
(2) Resonance effect operates through a `sigma`-bond
(3) Inductive effect operates through a `sigma` -bond
(4) Resonance effect operates through a `pi-`bond
(5) Resonance and inductive effects operate through `sigma`-bond

A

3 and 4

B

1 and 2

C

2 and 4

D

1 and 3

Text Solution

Verified by Experts

The correct Answer is:
A
The inductive effect is transmitted through `sigma` bond and weakens as the distance between the substituents and the reactive centre increases. But in resonance `pi` electrons shifting takes place consecutively giving permanent polarity on the chain.
