General

1.      Relative pronouns do two jobs at once:
a) acting as subject or object of a verb
b) joining two clauses together

2.      The most common are: who, whom, which and that — who and whom for people and which for things.

3.      Whom is not used much in conversation and refers to an object of a verb or a preposition.

4.      That can often replace whom, who and which.

5.      After nouns referring to times and places, when and where can be used to mean at which or in which and why can be used to mean for which.
