Melting point of calcium halides decreases in the order

1.	Melting point of calcium halides decreases in the order
Answer» `CaF_(2) gt CaCl_(2) gt CaBr_(2) gt CaI_(2)` `CaI_(2) gt CaBr_(2) gt CaCl_(2) gt CaF_(2)` `CaBr_(2) gt CaI_(2) gt CaF_(2) gt CaCl_(2)` `CaCl_(2) gt CaBr_(2) gt CaI_(2) gt CaF_(2)` SOLUTION :`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.
