In the formation of TC-bond, the atomic orbitals overlap in such a way that

A)  their axes remain parallel to each other and perpendicular to the internuclear axis

B)  their axes remain parallel to each other and parallel to the internuclear axis

C)  their axes remain perpendicular to each other and parallel to the internuclear axis

D)  their axes remain perpendicular to each other and perpendicular to the internuclear axis

Correct Answer: A

Solution :

 A\[\pi -\]bond is formed by sidewise or parallel overlapping between atomic orbitals. During this their axes remain parallel to each other and perpendicular to the internuclear axis.
