Question

identify the properties of hydrophilic molecules. 1 they are non - polar and dissolve in water. 2 they are non - polar and do not dissolve in water. 3 they are polar and can dissolve in water. 4 they are polar and do not dissolve in water. report feedback or error

Explanation:

Hydrophilic molecules are polar (since water is polar, and "like dissolves like"). Polar molecules can dissolve in water (hydrophilic means "water - loving"). Let's analyze each option:

• Option 1: Says non - polar and dissolve in water. Non - polar molecules don't dissolve in water, so wrong.
• Option 2: Says non - polar and do not dissolve in water. Hydrophilic molecules are polar and dissolve in water, so wrong.
• Option 3: Says polar and can dissolve in water. This matches the properties of hydrophilic molecules (polar nature and ability to dissolve in water).
• Option 4: Says polar and do not dissolve in water. Polar molecules (hydrophilic) do dissolve in water, so wrong.

Answer:

1. They are polar and can dissolve in water.
