Vedclass · Answer

(A) The melting point of ionic compounds depends on the lattice energy and the nature of the bond. According to Fajan's rule,as the size of the anion increases $(F^- Greater covalent character leads to a decrease in the melting point. Therefore,the melting point decreases as the size of the halide ion increases. The correct order is $CaF_2 > CaCl_2 > CaBr_2 > CaI_2$.

Which of the following is the correct decreasing order of the melting points of calcium halides?
