Also oxygen being the most electronegative would be termed as the negative end and the atom closest to it would be carbon. HCl is a polar molecule and the chlorine atom closest to negative side because of electronegativity of the chlorine atom is higher than hydrogen so that it pulls shares pair of electrons from H atom as a result formation of partial positive charge on hydrogen and negative charge on chlorine atom. Nitrogen 3. Is the molecule CO2 polar or nonpolar? The electronegativity difference between C and F is 1.5 so the C-F bond is polar.
