• ## What causes the difference in bond angles in carbon dioxide and water? A) the distance between the atomsin either molecules B) the facr that there are tei oxygen atoms in carbon dioxide and only one in water C) the fact that the number of lone pairs of electrons on the central atom is greater in the case of water D) the presence of a carbon atom in carbon dioxide E) the presence of a hydrogen atom in water

Answer is: C) the fact that the number of lone pairs of electrons on the central atom is greater in the case of water. Carbon(IV) oxide is nonpolar because CO₂ is linear molecule and the oxygen atoms are symmetrical (bond angles 180°). Water is polar because of the bent shape of the molecule. Oxygen atom
