Question

What is the difference between Inductive effect & Mesomeric effect?

Answer 1

Inductive Effect	Mesomeric Effect
1. It operates in saturated compounds.	1. It operates in unsaturated compounds especially having conjugated systems.
2. It involves electrons of a – bonds.	2. It involves electrons of π – bonds or lone pair of electrons.
3. The electron pair is slightly displace from its position and hence partial charges are developed.	3. The electron pair is completely transferred and hence unit positive and negative charges are developed.
4. It is transmitted over a short distance it becomes negligible after second carbon atom in the chain.	4. It is transmitted through the entire chain provided conjugation is present.
