## organic chemistry – Sp5 hybridization in cyclopropane?

The Question : 26 people think this question is useful I have never before heard/read about something as a $sp^5$ hybridization. Today, Henry Rzepa’s blog post made me aware of the existance of such a bonding system. That made me search a little bit and I found an entry in a german chemistry forum, where

## hybridization – What makes banana bonds possible in diborane?

The Question : 49 people think this question is useful Diborane has the interesting property of having two 3-centered bonds that are each held together by only 2 electrons (see the diagram below, from Wikipedia). These are known as “banana bonds.” I’m assuming there is some sort of bond hybridization transpiring, but the geometry doesn’t
