brought into play at the requirement of
attacking reagent?
(A)
Inductive effect
(BY
Mesomeric effect
Electromeric effect
ver
(D)
Inductomeric effect​

Answer 1

Answer:

Electromeric effect

Explanation:

Electromeric effect is a temporary effect brought into play at the requirement of attacking reagent.

Answer 2

The electromeric effect  and Inductomeric effect is the temporary effect brought into play at the requirement of attacking reagent.

What is Electromeric effect?

• Complete shifting of the pi electrons to one of the bonded atoms in the presence of attacking reagents.
• It is a temporary effect.
  

What is Inductive effect?

• The displacement of the sigma electrons towards the more electronegative element.
• It is a permanent effect.

What is Mesomeric Effect?

• The polarity produced in a conjugated system as a result of interaction between the pi bonds or pi bond and lone pair.
• It is a permanent effect.

What is Inductomeric effect?

• It increases the inductive effect in the presence of the attacking reagent.
• It is a temporary effect.

Thus,the electromeric and Inductomeric effects are temporary effects that occur when the attacking reagent approaches the molecule.
