Question

${FClO}_3$ (perchloryl fluoride) has the highest dielectric constant.

• A. True
• B. False

Answer 1

The correct option is A True

The dielectric constant is the ratio of the permittivity of a substance to the permittivity of free space. It is an expression of the extent to which a material concentrates electric flux, and is the electrical equivalent of relative magnetic permeability.
As the dielectric constant increases, the electric flux density increases, if all other factors remain unchanged. This enables objects of a given size, such as sets of metal plates, to hold their electric charge for long periods of time, and/or to hold large quantities of charge.
Due to higher electronegativity constituent atoms, $FCl{O}_3$ have very high dieelectric constant.
