1. In CBSE Class 11 Chemistry chapter 4 notes, what are the types of overlapping in covalent compounds?
Answer (1)
Ans- Sigma(σ) bond: Sigma bond is also termed as head-on overlap or axial overlap.
This type of covalent bond is formed when the overlapping is done from end to end along the internuclear axis. This may include the overlapping as follows:
• s-s overlapping
• s-p overlapping
• p–p overlapping
pi(π ) bond: The type of overlapping can be seen in a covalent bond that is formed when the bonding orbitals overlap sidewise, such that their axes are parallel to each other but perpendicular to the internuclear axis.
