Having trouble with irony in Julius Caesar?

I have to do an essay on Julius Caesar and the prompt is, "Some critics claim the title of Julius Caesar is ironic because the protagonist is Brutus. In a well developed essay, explain if this is true. Be sure to refer to other examples of irony that occur in the play." All I am asking is what kind of verbal, dramatic irony and irony of situation in the play will help me with my essay. I need an answer within a day because this essay is due on Monday well the rough draft. Thank you
