### sigma and pi bonds

So just to clarify, sigma bonds are only between two s orbitals, a P and an S orbital, or two P orbitals?

### Re: sigma and pi bonds

No, sigma bonds are not limited to just those pairs of orbitals. A sigma bond is just defined as being formed by head-on overlapping between orbitals, meaning other orbitals (ex. dz2 - dz2) can also have sigma bonds.

### Re: sigma and pi bonds

A sigma bond is just a bond is just the first bond formed between two atoms. Any additional (double, triple, etc.) are considered pi bonds

### Re: sigma and pi bonds

there is a sigma bond in every bond
single bond - 1 sigma bond
double bond - 1 sigma, 1 pi
triple bond - 1 sigma, 2 pi
