1. Are the following soluble, insoluble, or partially soluble.

- Benzophenone in hexane?
- 1-octanol in hexane? I think soluble?
- 1-butanol in water? in hexane?
- methyl alcohol in hexane? I think partially soluble?

Please help me and explaining would be greatly appreciated.

I wouldn't think benzophenone to be that polar; therefore, I would think it would be soluble in hexane.

1-octanol is insoluble in water (The Merck Index) therefore, probably soluble in hexane.

1-butanol; 9.1 mL soluble in 100 mL water @ 25 celsius according to The Merck Index. Miscible in ether; therefore, probably soluble (or at least partially soluble) in hexane.

Methyl alcohol. According to The Merck Index, MeOH is miscible with benzene; therefore, I would think it would be soluble in hexane

50.0 mL of water and 50.0 mL of hexane are placed in the same flask. 5.0 g of salicylic acid are added to this mixture, the flask is capped and the mixture is thoroughly shaken, not stirred. What will be the result?

- Benzophenone in hexane: Benzophenone is soluble in hexane. Hexane is a nonpolar solvent, and benzophenone is also nonpolar, so they are compatible and form a homogeneous solution.

- 1-octanol in hexane: 1-octanol is soluble in hexane. Both 1-octanol and hexane are nonpolar compounds, so they can mix well and form a solution.

- 1-butanol in water: 1-butanol is partially soluble in water. 1-butanol contains both a polar hydroxyl group and a nonpolar alkyl chain. The hydroxyl group can form hydrogen bonds with water molecules, allowing some 1-butanol to dissolve in water. However, the nonpolar alkyl chain makes 1-butanol more soluble in less polar solvents like hexane. Overall, it is considered partially soluble in water.

- 1-butanol in hexane: 1-butanol is soluble in hexane. Both 1-butanol and hexane are nonpolar compounds, so they can mix well and form a solution.

- Methyl alcohol in hexane: Methyl alcohol (methanol) is partially soluble in hexane. Methanol is a polar compound due to the hydroxyl group, while hexane is nonpolar. The polar nature of methanol allows it to dissolve in small amounts in hexane, making it partially soluble.

To determine the solubility of a compound, we need to consider the nature of the compound and the solvent it is being dissolved in. Let's analyze each compound one by one:

1. Benzophenone in hexane:
Benzophenone is an organic compound which is non-polar in nature. Hexane is also a non-polar solvent. When a non-polar compound like benzophenone is dissolved in a non-polar solvent like hexane, they tend to be soluble. Therefore, benzophenone is soluble in hexane.

2. 1-octanol in hexane:
1-octanol is also an organic compound but has a polar hydroxyl group. Hexane, on the other hand, is non-polar. When a polar compound like 1-octanol is dissolved in a non-polar solvent like hexane, it tends to be partially soluble. Some of the 1-octanol will dissolve in hexane, but not completely. So, you are correct in saying that it is partially soluble.

3. 1-butanol in water and hexane:
1-butanol is an organic compound with a polar hydroxyl group. Water is a polar solvent, so 1-butanol tends to be soluble in water. However, hexane is non-polar, so 1-butanol tends to be insoluble or only slightly soluble in hexane.

4. Methyl alcohol in hexane:
Methyl alcohol (also known as methanol) is a polar compound due to the presence of the hydroxyl group. Hexane is non-polar. In this case, a polar compound like methyl alcohol is not likely to dissolve well in a non-polar solvent like hexane. So, you are correct in saying that methyl alcohol is partially soluble in hexane.

Remember, these are generalized predictions based on the nature of the compounds and solvents involved. Actual solubility can also depend on factors like temperature and concentration. It is always good practice to conduct experiments or consult solubility charts for more accurate information.
