Write the formation of sigma covalent bond diagrammatically. |
|
Answer» Solution :It is a covalent bond formed by axial overlapping of half filled atomic orbitals ALONG the internuclear AXIS. Axial overlapping is ALSO called end to end or HEAD to head overlapping. Example : 1. S-S overlapping : It involves overlap of two half filled s-atomic orbital. This occurs during the formation of H2 molecule. The bond is s-s s bond.  2. s-p overlapping : It involves overlap of half filled s orbital and half filled p-orbitals. This occurs during the formation of hydrogen halide molecule (HCL, HBr, Hl)
