Question

Why do molecular compounds have low melting and boiling points compared to ionic compounds?

Answer 1

Answer:

This is because the energy required to disrupt the intermolecular forces between molecules is far less than the energy required to break the ionic bonds in a crystalline ionic compound

Answer 2

Answer:

• The melting and boiling points of molecular compounds are generally quite low compared to those of ionic compounds. ... Ionic solids typically melt at high temperatures and boil at even higher temperatures. For example, sodium chloride melts at 801 °C and boils at 1413 °C.
