Answer: Option (b) is the correct answer.
Explanation:
Polarity is defined as the development of partial charges on the atoms of a molecule.
Whereas polarizability is defined as the ability or measure of how readily an electron cloud is able to get distorted. More is the polarizability more will be the electron is distorted in nature.
A dipole moment is defined as the measurement of the separation of two opposite electrical charges.
Thus, we can conclude that when the electron cloud of a molecule is easily distorted, the molecule has a high polarizability.
When the electron cloud of a molecule is easily distorted, the molecule has a high: b. polarizability.
An electron cloud can be defined as the region containing a group of electrons with negative charge that surrounds the atomic nucleus with respect to an atomic orbital.
Hence, an electron cloud is a system which comprises a group of electrons surrounding the atomic nucleus of an atom.
Also, the highest probability of finding an electron is in the electron cloud.
In Chemistry, the higher the distortion of the electron cloud of a molecule, the higher would be its polarizability and vice-versa.
In conclusion, a molecule has a high polarizability when the electron cloud of a molecule is easily distorted.
