Lipids are typically non-polar molecules, which means they are soluble in non-polar solvents. In contrast, they are generally insoluble in polar solvents due to the lack of interaction at the molecular level between non-polar lipids and polar solvents.
Let's analyze each solvent or solution given:
1. 2% aqueous KCl solution - This is an aqueous (water-based) solution and therefore polar. Lipids are insoluble in this solution. (Result: False)
2. CHCl₂ (Chloroform) - Chloroform is a non-polar solvent, so lipids are soluble in it. (Result: True)
3. CH₃(CH₂)₆CH₃ (Octane) - Octane is another non-polar solvent. Thus, lipids are soluble in it. (Result: True)
4. H₂O (Water) - Water is a highly polar solvent. Lipids are not soluble in water. (Result: False)
5. None of the above - This option means that the lipid is not soluble in any of the listed solvents, which is incorrect as discussed above. (Result: False)
Based on this analysis, the lipid will be soluble in CHCl₂ (Chloroform) and CH₃(CH₂)₆CH₃ (Octane).
The resulting solubility for lipids in the given solvents is:
- 2% aqueous KCl solution: False
- CHCl₂: True
- CH₃(CH₂)₆CH₃: True
- H₂O: False
- None of the above: False
Hence, the answer is:
[False, True, True, False, False]
