Generally, if introduces a conditional clause-- if I see you, then I will kiss you-- while whether is used when you wish to consider two alternatives-- I cannot decide whether to kiss you or hit you.

If you find yourself unsure of which situation you are dealing with, then either will probably work synonymously.
