Do molecular shapes really matter?

We all have learnt about how water molecule is "bent" , SF ₆   is octahedral  , etc but does it affect the macroscopic substance we see? if it does , how does it affect it.

The bent shape of a water molecule makes it polar, and contributes to it being an excellent solvent. Life started in water, because of all the cool stuff dissolved in it. So yeah, shape is pretty important!

Proteins are molecules with complicated shapes, and the shapes determine their properties. 

The double-helix of DNA allows large amounts of information to be encoded and replicated. 

The macroscopic version of DNA is you)
