Bonding pairs present in co is ??
The hybridisation of Carbon in CO (Carbon Monoxide) is sp.
It can simply be found out by it's Lewis Structure, by completing their octets.
There is a triple bond between them with one lone pair on each atom. In that way both the atoms have their octets complete.
Thus, Steric No. = 1 (sigma bond) + 1 (lone pair) = 2.
This shows sp hybridisation in CO.
Elaborating the bonding :-
- There is one sigma (σ) bond and two pi (π) bonds made between C and O, since a triple bond contains one σ and two π bonds.
- The σ bond is made via a C2pz−O2pz head-on overlap. That is enough to make this bond, because each atom has one 2pz atomic orbital.
- The first π bond is made via a C2px−O2px sidewise overlap. That is enough to make this bond, because each atom has one 2px atomic orbital.
- The second π bond is made via a C2py−O2py sidewise overlap. That is enough to make this bond, because each atom has one 2py atomic orbital.
