Final answer:
Some compounds cannot interact with water because they are unable to form hydrogen bonds. Nonpolar molecules like fats and oils are hydrophobic and do not dissolve in water.Option 1 is the correct answer.
Step-by-step explanation:
The reason why some compounds cannot interact with water is because they are unable to form hydrogen bonds. Hydrogen bonds are a type of electrostatic interaction formed by the attraction of oppositely charged molecules. Water molecules are polar and can attract other polar molecules or ions, forming hydrogen bonds which make water a good solvent. However, nonpolar molecules like fats and oils do not dissolve in water and are considered hydrophobic because they do not interact well with water.
Water molecules are polar, with a positive and a negative end, enabling them to form hydrogen bonds with other polar or charged substances. The correct answer is 1) Because they are unable to form hydrogen bonds. Hydrophobic substances lack polar or charged regions, hindering interaction with water. Unlike hydrophilic compounds that readily form hydrogen bonds, hydrophobic molecules resist water due to their nonpolar nature. This causes them to aggregate away from water, explaining their insolubility. The inability to engage in hydrogen bonding results in water molecules excluding hydrophobic substances, leading to phenomena like the formation of oil droplets in water-based environments.
