The presence of unsaturation in a compound gives you a hint that a given group or compound is electron withdrawing group.

Lets take an example:

Carboxyl group is electron withdrawing because there is double bond in it.Similarly NO2 is also electron withdrawing group

And Hydroxyl group(OH) is electron donating group because there is no single bond in it.
