water is a polar solvent and hexane is a non - polar solvent.
determine which solvent each of the following is most likely to be soluble in.
sugar select an answer
ethanol, $\ce{c_{2}h_{5}oh}$ select an answer
oil select an answer

Explanation:

Step1: Recall the principle "like dissolves like"

The principle "like dissolves like" states that polar substances dissolve in polar solvents and non - polar substances dissolve in non - polar solvents.

Step2: Analyze the solubility of \(C_{12}H_{23}O_{11}\)

We know that water is a polar solvent and hexane is a non - polar solvent. \(C_{12}H_{23}O_{11}\) dissolves in water (polar solvent) but not in hexane (non - polar solvent). So, according to the "like dissolves like" principle, \(C_{12}H_{23}O_{11}\) must be a polar substance.

Step3: Analyze the solubility of Sugar

Sugar (sucrose, \(C_{12}H_{22}O_{11}\) - similar in nature to \(C_{12}H_{23}O_{11}\)) is a polar molecule. Since water is a polar solvent, sugar is soluble in water.

Step4: Analyze the solubility of Ethanol (\(C_{2}H_{5}OH\))

Ethanol has a polar - OH group. Water is a polar solvent, and ethanol can form hydrogen bonds with water. So ethanol is soluble in water.

Step5: Analyze the solubility of Oil

Oil is a non - polar substance (mostly composed of long - chain hydrocarbons). Hexane is a non - polar solvent, so oil is soluble in hexane (non - polar solvent) and not very soluble in water (polar solvent).

Answer:

For \(C_{12}H_{23}O_{11}\): polar substance (based on "like dissolves like" as it dissolves in polar water and not in non - polar hexane)
Sugar: soluble in water (polar solvent, sugar is polar)
Ethanol (\(C_{2}H_{5}OH\)): soluble in water (polar solvent, ethanol is polar)
Oil: soluble in hexane (non - polar solvent, oil is non - polar)
