Explain Why pentanoic acid and hexanol cannot dissolve completely in water?

Answer 1

Pentanoic acid and hexanol cannot dissolve completely in water because they are both non-polar molecules. Water is a polar molecule, meaning it has a partially positive and negative end. Non-polar molecules, such as pentanoic acid and hexanol, do not have a charge separation and are therefore not attracted to the polar water molecules. This leads to limited interactions between the non-polar molecules and water, resulting in poor solubility.
