Give three points of differences between inductive effect and resonance effect.

Difference between inductive effect and resonance effect is as follows

Inductive effect	Resonance effect
Inductive effect involves -electrons displacement and occurs only in saturated compounds	It involves -electrons or lone pair of electrons and occurs only in unsaturated and conjugated system.
Inductive effect can move upto 3-carbon atom	It is applicable all along the length of conjugated system.
In inductive effect, there is a slight displacement of electrons and thus only partial positive and negative charges appear.	In resonance effect, there is complete transfer of electrons, and thus full positive and negative charges appear.
