Question

How is geometrical symmetry related to the polarity of a molecule?

Answer 1

Explanation :

As we know that the geometrical symmetry of the molecule and the polarity of the bonds both are equally important for determining the polarity of the molecule.

The molecule that has zero dipole moment that means it is a geometrical symmetric molecule and the molecule that has some dipole moment that means it is a geometrical asymmetric molecule.

As the molecule is symmetric, the dipole moment will be zero and the molecule will be non-polar.

As the molecule is asymmetric, the dipole moment will not be zero and the molecule will be polar.

Thus, we can say that the a symmetry molecule is non-polar in nature and an asymmetry molecule is a polar molecule.

Answer 2

A symmetric shape means the bonds' polarities are exactly equal then it means the polarities cancel each other, resulting to a nonpolar molecule. This is because there will be no available polarity for other substance to attach.
