Question

which of the statements describe hydrogen bonding between water molecules or describe properties of water that lead to hydrogen bonding between water molecules? the slightly positive hydrogen atom is attracted to the slightly negative oxygen atom within a single water molecule. the slightly negative oxygen atom of one water molecule is attracted to the slightly positive hydrogen atom of another water molecule. a water molecule is nonpolar because it has a linear structure and its shared electrons are equally attracted to the oxygen atom and the hydrogen atoms. a water molecule is polar because it has a bent structure and its shared electrons are more attracted to the oxygen atom than the hydrogen atoms.

Explanation:

1. Analyze the first option: The attraction within a single water molecule is a covalent bond (O - H bond), not hydrogen bonding. Hydrogen bonding is between different molecules. So this option is incorrect.
2. Analyze the second option: Hydrogen bonding occurs between a slightly negative oxygen of one water molecule and a slightly positive hydrogen of another water molecule. This correctly describes hydrogen bonding between water molecules. So this option is correct.
3. Analyze the third option: A water molecule is polar, not non - polar. The structure of water is bent (not linear), and electrons are more attracted to oxygen, creating a dipole. So this option is incorrect.
4. Analyze the fourth option: A water molecule has a bent structure. Due to the higher electronegativity of oxygen, shared electrons are more attracted to oxygen, making the molecule polar. This polarity is a property that leads to hydrogen bonding (since polar molecules with H bonded to F, O, or N can form H - bonds). So this option is correct.

Answer:

• The slightly negative oxygen atom of one water molecule is attracted to the slightly positive hydrogen atom of another water molecule.
• A water molecule is polar because it has a bent structure and its shared electrons are more attracted to the oxygen atom than the hydrogen atoms.
