Radical Rules

Are there any rules for determining when a molecule will have a radical? If so what are they? Also, on the midterm, will we be required to determine if a molecule has a radical?

Thanks.

Radicals are in chapter 3, so a question regarding them on the midterm is possible. Radicals occur usually when there is an electron that is not part of a lone pair. An easy way to tell is if the compound has an odd number of outer electrons (the ones that go on the Lewis structure). To be sure you could draw the Lewis structure and see if there is a dot by itself.
