### Unhybridized Orbitals

How do you know when to use unhybridized orbitals vs. hybridized orbitals?

Look at bonding.

For example, ethylene makes a C::C and each C also makes 2 H bonds, therefore each C makes a total of 3 bonds = sp2. When you look at sp3, which is the full octet, sp2 is missing a p, and that is your un hybridized p. This is where the pi bonding happens.

I think in general, when atoms form covalent bonds, they hybridize orbitals because that's how sigma and pi bonds form
