### Pi bonds

Hi guys! So I'm a little confused on pi bonds. Are they just the overlapping of unhybridized p orbitals? Thanks!

Yes (at least that's the way I understand it).

### Re: Pi bonds

Actually overlapping bonds usually refers to sigma bonds. Pi bonds are really orbitals that are side by side.

### Re: Pi bonds

Pi bonds result from multiple bonds (double, triple, etc.), aka unhybridized oribtals. They're unhybridized because hybridization only takes into account regions of e- density, so the 2nd or 3rd bond doesn't "count" when calculating hybridization. Pi bonds bond on either side of the internuclear axis, so they can't be rotated or else that would completely change the molecular structure.

Hope that helps :)

### Re: Pi bonds

Pi bonds are basically 2 orbitals that overlap side by side. They also do not allow bound atoms to rotate and have e- density on each side of the internuclear axis.
