Whenever, anion and cation approach each other, the valence shell of the anion is pulled towards the uncleus of the anion is pulled towards the nucles of the cation and as a result, the shape of the anion gets cation is known as polarization of polarizing an amion by a cation is known as polarrization. The ability or capacity of a cation of polarizethe anion towards litsef, is known as its polarizing power. Similiarty. the ability or capacity of an anion to get polarized by the cation, is known as its polarizability. As a result of polarisation, the two ions tend to come closer and the ionic character of the ionic ond acquired partial covalent character. The magnitude of polarization depends upon a number of factors whihc were suggested by Fazan and are termed as Fazan rules.
Which has the minimum melting point ?

A

`CaF_(2)`

B

`CaCl_(2)`

C

`CaBr_(2)`

D

`Cal_(2).`

Text Solution

Verified by Experts

The correct Answer is:
D
`Cal_(2)` has minimum melting point due to maximum covalent character.
