Problem: Which of the following pairs of substances would you expect to form homogeneous solutions when combined?(a) CCl4 and  H2 O(b) KCl and H2O(c) Br2 and CCl4(d) CH3 CH2OH and H2O

FREE Expert Solution

Recall: The theory of like dissolves like states that compounds with similar intermolecular forces or polarity dissolve each other. The types of intermolecular forces possible are:

Ion-dipole interaction: the strongest type; occurs between ions from ionic compounds and dipole moments from polar covalent compounds.
Hydrogen bonding: occurs when H is bonded to an electronegative atom such as N, O, F.
Dipole-dipole interaction: occurs between polar covalent compounds.
London dispersion forces: the weakest type; occurs between nonpolar covalent compounds.
