Question

For the following solutions, circle the principal type of solute-solvent interaction:
(a) Pentane (C4H10) in cyclohexane (C6H14). [Hint: Pentane and cyclohexane are nonpolar.] Answer: ion-dipole forces, hydrogen bonding, dipole-dipole forces or dispersion forces (b) Potassium iodide (KI) in ethanol (CH3CH2OH).
Answer: ion-dipole forces, hydrogen bonding, dipole-dipole forces or dispersion forces (c) Calcium chloride (CaCl2) in water (H2O).
Answer: ion-dipole forces, hydrogen bonding, dipole-dipole forces or dispersion forces (d) Ethanol (CH3CH2OH) in water (H2O).
Answer: ion-dipole forces, hydrogen bonding, dipole-dipole forces or dispersion forces (e) HBr in methyl chioride (CH3Cl).
