Water is best described as which of the following?

• A. A non-polar molecule that repels most substances
• B. An ionic compound that forms strong bonds with solutes
• C. A polar molecule with a high capacity to dissolve many substances
• D. A hydrophobic molecule that does not interact with solutes

Answer: (C)

Verified step by step guidance

1. Understand the nature of water molecules: Water is composed of two hydrogen atoms and one oxygen atom, forming H₂O.
2. Recognize the polarity of water: The oxygen atom is more electronegative than the hydrogen atoms, creating a partial negative charge on the oxygen and a partial positive charge on the hydrogens, making water a polar molecule.
3. Consider the implications of polarity: Due to its polarity, water can form hydrogen bonds with other polar molecules and ions, allowing it to dissolve many substances effectively.
4. Evaluate the options: A non-polar molecule would not have the same dissolving capabilities as water. An ionic compound forms ionic bonds, not characteristic of water. A hydrophobic molecule repels water, which is contrary to water's properties.
5. Conclude with the correct description: Water is best described as a polar molecule with a high capacity to dissolve many substances, due to its ability to form hydrogen bonds with solutes.
