I got a 5 on the AP Chem exam last year, and as far as I know, you don't have to memorize any of those. Unless they drastically changed everything this year, you definitely don't really have to know the Bragg equation or how to find the edge length of unit cells (etc). I don't believe that you have to know the names of unit cells either (but I'm not 100% sure on this).
The only place the Clausius-Clapeyron might appear is in the free response section, and if it appears here, they will give you the equation.
