Melting point of calcium halides decreases in the order

A

`CaF_(2) gt CaCl_(2) gt CaBr_(2) gt CaI_(2)`

B

`CaI_(2) gt CaBr_(2) gt CaCl_(2) gt CaF_(2)`

C

`CaBr_(2) gt CaI_(2) gt CaF_(2) gt CaCl_(2)`

D

`CaCl_(2) gt CaBr_(2) gt CaI_(2) gt CaF_(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
`CaF_(2) gt CaCl_(2) gt CaBr_(2) gt CaF_(2)` . As the size of the anion increases, the covalent character increases and hence the melting points decrease.
