In chemistry, one of the golden rules is that "Structure" leads to a certain "Shape" and "Shape" in turn leads to "Reactivity". "Reactivity can be interpreted as the behavior of a given molecule.

For the purposes of discussion, can you provide an example of a molecule or a compound whose shape leads to a certain type of behavior? Pick a molecule or a compound, use VSEPR to predict its shape, and explain how this shape is responsible for a certain behavior observed in that molecule or compound.

For example CO2 is linear and due to this shape, the molecule though it contains two polarized C-O bonds, ends up being non-polar as a whole. This causes CO2 to have fewer interactions with other molecules and makes it less attractive. So, in the end, CO2 behaves as a gas and has very low melting and boiling points. If CO2 was not linear but bent perhaps it would be more polar and be a liquid!
