Pi bonds are produced by overlapping of__________________?
Correct answer: A. Un-hybrid orbitals
- A. Un-hybrid orbitals
- B. Hybrid orbitals
- C. Hybrid and un hybrid orbitals
- D. atomic orbital and hybrid orbital
Explanation
A pi bond forms by sideways overlap of parallel, unhybridized atomic orbitals, usually p orbitals, above and below the internuclear axis. Students may choose hybrid orbitals because sigma bonds commonly involve hybrid orbitals, but hybrid orbitals point along the axis and mainly form sigma bonds.

About Sigma and Pi Bonds
A sigma bond forms by direct end-to-end overlap along the internuclear axis, whereas a pi bond forms by sideways overlap of parallel orbitals. The topic covers single, double and triple bonds, bond composition, restricted rotation and the relation between sigma and pi bonding and orbital hybridisation.
