Question

15. Choose correct options
A. Which of the following statements are true
with respect to electronic displacement in
covalent bond ?
a. Inductive effect operates through it bond
b. Resonance effect operates through
bond
c. Inductive effect operates through o bond
d. Resonance effect operates through it
bond
i. a. and b
ii. a and c
iii. c and d
iv. b and c​

Answer 1

Answer:

1 option a and b are right answer

Answer 2

Inductive Effect operates through σ bond.

Resonance Effect operates through π bond.

Explanation:

Inductive effect operates through σ bond.

Inductive effect is permanent but weak effect involving displacement of σ electrons towards more electronegative species.

It can be transmitted through a chain of C atoms.

Resonance effect operates through π bond.

A simple example given in attachments illustrates Resonance effect in 1,3-butadiene.
