There are 4 conditionals for using if in any sentence

1. 0 conditional- for use in scientific facts or general truths. If is used as a substitute to when
2. 1 conditional- used with will/can+ base verb for possible future result.
3. 2nd conditional- used with simple past + modal base verb for impossible or unreal situations
4. 3rd conditional- past perfect+ modal+ have+ past participle for expressing a past regret about something which did not happen in the past.
