Determine the shape of the molecule and determine if any of the individual bonds are polar (you need an electronegativity table for this). If the molecule has only nonpolar bonds, then it is non polar. If the molecule has some polar bonds, determine if the molecule is perfectly symmetrical. If it is, most likely the molecule is nonpolar. If not, then it is most likely polar. Written Nov 2, 2013 Â· View Upvotes.
