Valence Bond Theory

In which of the following molecules both phenyl rings are not coplanar ?

Which of the following plot represents potential energy of a pair of nuclei as a function of their separation:

Which one of the following does not have ${\mathrm{sp}}^2$ hybridised carbon ?

The correct statement for the structure of ${\mathrm{P}}_4{\mathrm{O}}_{10}$ is

The $\mathrm{p\pi }-\mathrm{d\pi }$ bonding depends on the lone pair of electron donors and _____ of an acceptor.

The $\mathrm{p\pi }-\mathrm{d\pi }$ bonding depends on the electrons donors and vacant orbitals of an acceptor.

The $\mathrm{p\pi }-\mathrm{d\pi }$ bonding depends on the _____ donors and vacant orbitals.

There is bonding between two atoms where one atom is having one vacant orbital and another is having one lone pair of electrons. The bond is known as $\mathrm{p}\left(\mathrm{pi}\right)-\mathrm{p}\left(\mathrm{pi}\right) \mathrm{or} \mathrm{p}\left(\mathrm{pi}\right)-\mathrm{d}\left(\mathrm{pi}\right)$.

Define $\mathrm{p\pi }-\mathrm{d\pi }$ bond.
