Rank the solvents according to their polarities, from the most polar to nonpolar.

ethyl acetate, water, acetone, hexane, ethanol

To rank the solvents according to their polarities, you can consider the relative polarities of their functional groups or the polarity of their molecules as a whole. In general, solvents with polar functional groups or a higher dielectric constant are more polar.

Here is a ranking of the solvents according to their polarities, from the most polar to nonpolar:

1. Water: Water is a highly polar solvent due to its ability to form hydrogen bonds. It has a high dielectric constant and is often used as a reference for polarity.
2. Ethanol: Ethanol has a hydroxyl group (-OH) which makes it polar. Its polarity is lower compared to water but higher than other solvents on the list.
3. Acetone: Acetone is a polar solvent, but not as polar as water or ethanol. It contains a polar carbonyl group (C=O) which gives it some polarity.
4. Ethyl acetate: Ethyl acetate has a carbon-oxygen double bond (C=O), which increases its polarity compared to acetone.
5. Hexane: Hexane is a nonpolar solvent as it contains only carbon and hydrogen atoms. It lacks polar functional groups and has a low dielectric constant, making it the least polar solvent in this list.

Remember that this ranking is based on general polarities and can vary depending on the specific application or criteria used for classification.

To rank solvents according to their polarities, we need to consider their chemical structures and functional groups. Polar solvents are able to dissolve polar compounds, while nonpolar solvents dissolve nonpolar compounds.

One way to determine the polarity of a solvent is by considering its dielectric constant or permittivity. A higher dielectric constant indicates a more polar solvent. However, discussing the absolute polarities of solvents can sometimes be subjective, as it depends on the specific context and the compounds being dissolved.

Here's a suggested ranking of the solvents from the most polar to nonpolar based on their relative polarities:

1. Water: Water is a highly polar solvent due to its ability to form hydrogen bonds. It has a high dielectric constant, making it the most polar solvent among the given options.

2. Ethanol: Ethanol also has a significant polarity due to the presence of the hydroxyl (-OH) group. It can form hydrogen bonds and exhibits a relatively high dielectric constant.

3. Ethyl Acetate: Ethyl acetate contains both a polar carbonyl (C=O) group and a nonpolar ethyl group. Although it is polar, it is less polar than water and ethanol.

4. Acetone: Acetone is a polar solvent with a carbonyl group (C=O). Its polarity is in between ethyl acetate and hexane.

5. Hexane: Hexane is a nonpolar solvent. It lacks any functional groups that would give rise to significant polarity. It has a low dielectric constant, making it the least polar among the given solvents.

Please note that this ranking is a general approximation and can vary depending on specific scenarios or the compounds being dissolved.

Water is the most polar. hexane is the least.
