There is an attraction between a small, weakly electronegative hydrogen atom and a large, strongly electronegative atom of fluorine, nitrogen, or oxygen. There is an attraction between a small, highly electronegative hydrogen atom and a large, highly electronegative fluorine atom.

Answer: Molecular geometry is used to determine the shapes of molecules. Explanation: The shape of a molecule helps to determine its properties. For example, carbon dioxide is a linear molecule. This means that #CO_2# molecules are non-polar and will not be very soluble in water (a polar solvent). Other molecules have different shapes.

Chemical Bonding : Polarity II: Molecular Shape Quiz. Polarity is also determined by the shape of a molecule. Molecules that are symmetrical tend to be nonpolar. Molecules that are asymmetrical tend to be polar. Polarity is like a game of tug-o-war. If there is an equal "pull" on the central atom from all sides, then the molecule is nonpolar.
