Question

Which pair(s) of compounds will form a solution? Check all that apply.

a) Sodium chloride (NaCl) and hexane (C₆H₁₄)
b) Octane (C₈H₁₈) and carbon tetrachloride (CCl₄)
c) Methanol (CH₃OH) and water (H₂O)
d) Cyclodecanone (C₁₀H₁₈O) and water (H₂O)
e) None of the above

Answer 1

Sodium chloride (NaCl) and hexane (C6H14) will not form a solution. Octane (C8H18) and carbon tetrachloride (CCl4) will not form a solution. Methanol (CH3OH) and water (H2O) will form a solution. Cyclodecanone (C10H18O) and water (H2O) will form a solution.

Step-by-step explanation:

In order for compounds to form a solution, they must have similar intermolecular forces.

a) Sodium chloride (NaCl) and hexane (C6H14) will not form a solution because NaCl is an ionic compound and hexane is a nonpolar covalent compound. They have different intermolecular forces.

b) Octane (C8H18) and carbon tetrachloride (CCl4) will not form a solution because they are both nonpolar covalent compounds with similar intermolecular forces.

c) Methanol (CH3OH) and water (H2O) will form a solution because they are both polar compounds with similar intermolecular forces.

d) Cyclodecanone (C10H18O) and water (H2O) will form a solution because they are both polar compounds with similar intermolecular forces.

e) None of the above.
