b.) require a great deal of energy to break.

Most ionic compounds exist as solids at room temperature. In order to melt or boil an ionic compound, the ionic bonds must be broken. It takes a great deal of energy to break an ionic bond. For this reason, ionic solids have high melting and boiling points.
