A molecule in which centre of gravity of positive nuclei and revolving electrons coincide is

A molecule in which centre of gravity of positive nuclei and revolving electrons do not coincide is

A molecule in which centre of gravity of positive nuclei and revolving electrons do not coincide is

The centre of gravity

In non-polar molecules, centre of gravity of positive nuclei and revolving electrons

Assertion: Polar mlecules have permanent dipole moment. Reason : In polar molecule, the centres of positive and negative charges coincide evcen wehen there is no external field.
