Question

what Is sigma bond ? how many types of overlapping leads to the formation of sigma bond . explain each type of overlapping .​

Answer 1

Answer:

There are two types of overlapping orbitals: sigma (σ ) and pi (π ). Both bonds are formed from the overlap of two orbitals, one on each atom. σ bonds occur when orbitals overlap between the nuclei of two atoms, also known as the internuclear axis.

Answer 2

A Sigma bond is a kind of covalent bond.

• A sigma bond is a covalent bond that is formed by head-on overlapping of the atomic orbitals.
• Sigma bond is formed by two types of overlapping which are head-on overlapping and end-to-end overlapping.
• Head-on overlapping is the one in which atomic orbitals are attached from head to head.
• End-to-end overlapping is the one in which atomic orbitals are joined from the ends of each other.
