M/B POINT

All ionic compounds have high melting and boiling points due to the strong electrostatic forces between ions. This means that it takes a lot of heat energy to break them apart.

Simple molecular substances have very low melting and boiling points and are gases at room temperature. This is because the intermolecular forces are…
