Why cant you just answer his question? The answer to the worksheet you are doing is covalent bonds
Intermolecular forces are the forces of attraction that exist between molecules in a compound. The stronger the attractions between particles the more difficult it will be to separate them. When substances boil, the particles are completely separated from one another and the attractions between the molecules are completely overcome.
Calcium fluoride is an example of an ionic compound, not a covalent compound. Covalent compounds form between two nonmetals, while ionic compounds form between a metal and a nonmetal.
Ionic compounds contain ionic compounds whereas molecular compounds contain covalent bonds in their molecules.
Electrical attractions between atoms form chemical bonds.
Compounds, particles made up of more than one element, are held together by electrostatic attractions--called bonds--between the negatively-charged electrons of one atom and the positively-charged proton of another. The bonds in a compound are generally formed when two atoms get close enough together for this attraction to form a bond between them, connecting them. Different atoms have different attractions to other atoms depending on the number of electrons that can be bonded to the other atom. In order to break apart a compound, therefore, you must break the bond between the atoms in that compound. This can be done when one atom in the compound comes across an outside atom that it is more attracted to. That atom will then bond with the new atom and the compound will be broken. Bonds can also be broken when energy (usually in the form of heat) is applied to the compound. Different bonds have different strengths and therefore different amounts of energy that must be added in order to break the bond.
Polar compounds have stronger attractions between molecules.

ionic compounds are polar compounds because they have charge separation between them
A mixture consists of multiple compounds rather than the compound which consists of different elements. A mixture can be separated more easily into its components and has weak and strong intermolecular attractions verses the consistently strong intermolecular bonds between atoms.

Compounds differ because of differences in attractions between their molecules.
