### Conceptual Question

What is the significance of learning about hybridization and sigma vs. pi bonds? Does it affect the chemical or physical properties of the molecule in any way?

Yes, sigma bonds allow bound atoms to rotate (as they are only bonded with a single bond) whereas pi bonds do not allow bound atoms to rotate (as they are bonded with a double bond). Since pi bonds don't allow atoms to rotate, these bonds are more rigid.

Knowing the difference between sigma and pi bonds allows you also to know better the distribution of electron density! With pi bonds, there is electron density on either side of the internuclear axis but with the sigma bonds, there's cylindrical symmetry around the axis!
