      Why do ionic compounds have high melting points?       [NCERT, CBSE (AI) 2008C]     

    Answer:

                      The ionic compounds are made up of positive and negative ions. There is a strong force of attraction between the oppositely charged ions, therefore a lot of energy is required to break this force of attraction and melt this ionic compound. That is why, ionic compounds have high melting points.
