Q.
pi $\left(\right.\pi \left.\right)$ bond is formed by the overlap of
NTA AbhyasNTA Abhyas 2020Chemical Bonding and Molecular Structure
Solution:
In the formation of pi bond the atomic orbitals overlap in such a way that their axes remain parallel to each other and perpendicular to the internuclear axis. The orbitals formed due to sidewise overlapping consist of two saucer type charged clouds above and below the plane of the participating atoms.
