The answer is 90 and 180. NO 2-has one more electron than NO 2, so it has a non-bonding pair ("lone pair") of electrons on nitrogen. The bond pairs are at an angle of 120° to each other, and their repulsions can be ignored. For example, carbon dioxide and nitric oxide have a linear molecular shape. 3) Water (H 2 O): * It is evident from the Lewis structure of water molecule, there are two bond pairs and two lone pairs in the valence shell of oxygen. Here, SF4 bond angles are around 102 degrees in the equatorial plane and around 173 degrees between the axial and equatorial positions. XeF2 is a linear molecule due to the arrangement of fluorine atoms and the lone pairs of electrons in the symmetric arrangement. d. formal charge on each atom? How do I work this problem out? Because the lone pair of electrons occupies more space than the bonding pairs, we expect a decrease in the Cl–Sn–Cl bond angle due to increased LP–BP repulsions.
