Pi bonds.

Pi (π) bonds are formed from the sideways overlap of adjacent p orbitals. The two lobes that make up the π bond lie above and below the plane of the σ bond. This maximises overlap of the p orbitals. A single π bond is drawn as two electron clouds, one arising from each lobe of the p orbitals. The two clouds of electrons in a π bond ...A pi bond (π bond) is a type of covalent bond that results from the side-by-side overlap of two p orbitals, as illustrated in Figure \(\PageIndex{4}\). In a π bond, the regions of orbital overlap lie on opposite sides of the internuclear axis. Along the axis itself, there is a node, that is, a plane with no probability of finding an electron.A pi bond is side by side overlap. There is overlap above and below this sigma bond here and that's going to prevent free rotation.
