1.

Write any three differences between sigma band and pi bond.

Answer»

Sigma bond(σbonds)

1. The covalent bond formed by the overlap of atomic orbitals along the internuclear axis is called sigma bond.

2. The overlapping orbitals are oriented along the internuclear axis.

3. The bond is rotationally symmetrical around the internuclear axis

Pi bond(π bonds)

1. The covalent bond formed by the lateral overlap of two p orbitals which are mutually parallel but oriented perpendicular to the internuclear axis is called a pi bond.

2. The overlapping orbitals are oriented perpendicular to the inter nuclear axis.

3. The bond is not rotationally symmetrical around the internuclear axis.
