Hi all,

 I was just trying to find out the reaction or place were carbon can have 5 bonds.

I have seen before were carbon had 5 bonds to it, it was an intermediate to some reaction, long time ago,

I was wondering if anybody had any ideas as to what reaction/ intermediate this coulda have been, or knows other reactions to were carbon can have 5 bonds to it.

i' am just curious to find out


thx

Carbon doesn't have 5 bonds. However, the intermediate to an Sn2 reactions is sometimes drawn as if the newly forming bond and the breaking bond are both in place at the same time, so it looks like a carbon with 5 substituents.

Maybe you were looking for the cation CH₅⁺   http://en.wikipedia.org/wiki/CH5%2B ?

Remark, in this case the carbon atom is considered to have four bonds with five hydrogen atoms.
I don't know any compound where a carbon would have five bonds. Carbon atoms don't have five bonds.
