MCQ
Pi bond is formed:
- ABy the overlapping of atomic orbitals on the axis of nuclei.
- BBy mutual sharing of p - electrons.
- CBy sideways overlapping of half filled p - orbitals.
- DBy overlapping of s-orbitals with p - orbital.
Explanation:
If a bond between two atoms is broken when one atom is rotated around the bond axis, that bond is called a pi bond.
Pi bonds are formed by the sideways overlap of parallel half filled p−orbitals on adjacent atoms as shown in the figure.
They are not formed from hybrid orbitals.
