Verified step by step guidance

Understand the concept of miscibility: Two solvents are miscible if they can mix in all proportions without separating into two phases. This usually depends on the polarity of the solvents and their ability to form intermolecular interactions like hydrogen bonds.

Analyze the polarity of each solvent: Water is a highly polar solvent capable of hydrogen bonding. Hexane and benzene are nonpolar solvents, while ethanol and diethyl ether are polar but less so than water.

Compare solvent pairs based on polarity and hydrogen bonding: Water and ethanol are both polar and can form hydrogen bonds, making them miscible. Hexane and water, as well as benzene and water, have very different polarities and do not mix well.

Consider diethyl ether and water: Diethyl ether is somewhat polar and can interact with water, but its miscibility is limited compared to ethanol. It is partially miscible but not fully miscible in all proportions.

Conclude that the pair water and ethanol is miscible due to similar polarity and hydrogen bonding capability, while the other pairs are either immiscible or only partially miscible.
