Question

Give ny two differentence between Inductive
and Resonance effect [Mesomeric effect].
effect​

Answer 1

Inductive effect(1 2 3) &Resonance effect(1.2.3.)

1 It involves displacement of a electrons in saturated compounds.

1. It involves displacement of % electrons or lone pair of electrons in unsaturated and conjugated compounds.

2 In inductive effect, there is slight displacement of σ electrons and partial +ve or-ve charge develops.

2. In this effect, there is complete transfer of π electrons and as a result, complete +ye or -ye charge develops.

3 Inductive effect can move only upto 3 to 4 carbons.

3.In this case, movement of electrons all along the length of conjugated system takes place.

Answer 2

Answer:

Inductive effect

1. It operates in saturated compounds.
2. it envolves electrons of a bonds.
3. The electron pair is slightly displace from its position and hence partial charges are developed.
4. It is transmitted over a short distance it becomes negligible after second carbon atom in the chain.

Mesomeric effect

1. It operates in unsaturated compounds especially having conjugated systems.
2. It involves electrons of π – bonds or lone pair of electrons.
3. The electron pair is completely transferred and hence unit positive and negative charges are developed.
4. It is transmitted through the entire chain provided conjugation is present.
