Re: Polar/nonpolar molecules
Polarity is essentially the distribution of charge throughout a molecule. Once you draw a lewis structure, identify the difference in electronegativity in the bonds of the molecule and that identification determines the relative difference in charge of the atoms in that bond. If there is a large dif...
