Question

The chemical bond formed by the overlapping of orbitals on the internuclear axis is:

• A. Pi bond
• B. Sigma bond
• C. Delta bond
• D. Phi bond

Hint:

Sigma bonds are the strongest type of covalent bond formed by the head-on overlap of orbitals.

Answer 1

The Correct Option is B

Step 1: Definition of Sigma Bond.
A sigma bond is formed by the head-on overlapping of atomic orbitals along the internuclear axis. This overlap results in a bond with high electron density between the nuclei. Step 2: Characteristics of Sigma Bond.
Sigma bonds are stronger than pi bonds due to the direct overlap of orbitals. They are formed in single bonds and are responsible for the bonding between atoms in molecules. Step 3: Conclusion.
The bond formed by the overlapping of orbitals along the internuclear axis is called a sigma bond.
