I want to ask two questions basically.

(1) How we can calculate area of small molecules like methane, ethane, phenol using Pymol ? I watched and read a lot but everything is about calculation for molecular surface of the protein not for small molecues. I have build the small molecules and converted my file into pdb sothat pymol can read it .

Now, I have no codes in hand to calculate its molecuar surface area.

The second question is

(2) where we can get dataset for small molecules ?
