Final answer:
The miscibility of liquids is influenced by their polarity, with polar liquids generally mixing with other polar liquids and nonpolar liquids being miscible with other nonpolar liquids. A polar liquid will typically not mix with a nonpolar liquid, illustrating the principle of 'like dissolves like.' The correct answer is a. Polar liquids cannot mix with nonpolar liquids.
Step-by-step explanation:
The miscibility of two liquids is closely related to their polarity. In general, polar liquids tend to mix with other polar liquids due to the electrostatic attraction, which includes hydrogen bonding and dipole-dipole interactions. These interactions are strong enough to allow the molecules of the solvents to mix.
On the other hand, nonpolar liquids are miscible with other nonpolar liquids because the dispersion forces acting between the molecules are uniform, which results in a uniform mixture.
Based on the options provided regarding the miscibility of liquids:
a. Polar liquids cannot mix with nonpolar liquids. This is generally true as the strong electrostatic forces in polar liquids and the weak dispersion forces in nonpolar liquids result in immiscibility.
b. Nonpolar liquids cannot mix with other nonpolar liquids. This statement is incorrect; nonpolar liquids can mix with one another.
d. Nonpolar liquids are miscible with other nonpolar liquids. This is correct as their similar intermolecular forces allow them to mix without resistance.
e. Polar liquids can mix with other polar liquids. This is correct due to the similarity of intermolecular forces within them.
The statements c and f are incorrect and can be disregarded.
