Webbe) Draw a diagram to show the shape of a molecule of SiCl 4. 2. The molecules BF 3 and NF 3 have similar formulae, but completely different shapes. Draw diagrams to show the shapes of the two molecules, and explain carefully why they are different. 3. In the molecules CH 4, NH 3 and H 2O, the bond angles are as follows: H-C-H H-N-H H-O-H … WebbChemical 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. ios 16 should you update
