After drawing it out, look at the surrounding atoms of the central atom. If the surrounding atoms are all the same, then the dipoles cancel out, thus the molecule has a non-polar shape (which is non-polar in general – but there are also covalent bonds to consider – where you look at electronegativity). Nov 15, 2016
