multiple bonds occur between
C and C
C and O
C and N
All of these
As we learnt in
Structure of Carbon dioxide -
Non planar linear molecule
- wherein
Due to maximum tendency to form multiple bond with oxygen
-
bonds are formed by overlapping of p-orbitals that are perpendicluar to the nuclear axis.
CO, CN, CC all show -
bonding.
