Carbon tetrachloride (CCl4) is a nonpolar covalent molecule, while calcium bromide (CaBr2) is an ionic compound.

When CCl4 and CaBr2 are mixed, the polar CaBr2 molecules will induce a dipole in the nonpolar CCl4 molecules. This will cause the carbon atoms in CCl4 to become slightly positive, and the chlorine atoms to become slightly negative. The positive carbon atoms will then attract the negative bromide ions, and the negative chlorine atoms will attract the positive calcium ions, forming ionic bonds between the two compounds.
