CO2, which has two carbon-oxygen bonds, is non polar because... the two carbon-oxygen bonds in CO2 are oriented 180 degrees from each other. Covalent bonds between identical atoms (as in H 2) are nonpolar—i.e., electrically uniform—while those between unlike atoms are polar—i.e., one atom is slightly negatively charged and the other is slightly positively charged. 91% (343 ratings) FREE Expert Solution. We will start by calculating the total number of valence electrons. Nonpolar. Depending on the arrangement of outer atoms, this molecule could be polar or nonpolar. Covalent- the small difference in electronegativity is the reason. Tags. Question = Is ClF3 polar or nonpolar? Polar and Non-Polar Molecules.
