Question

two water molecules are weakly drawn to one another, the slight positive of the hydrogens from one molecule is pulled towards the slight negative on the oxygen of the other molecule. what type of bond is occurring? a polar covalent b non-polar covalent c ionic d hydrogen

Explanation:

1. Recall the definitions of each bond type:

• Polar covalent bonds involve unequal sharing of electrons within a molecule (e.g., the O - H bond in water).
• Non - polar covalent bonds involve equal sharing of electrons (e.g., in \(O_2\) or \(H_2\)).
• Ionic bonds involve the transfer of electrons between atoms, resulting in charged ions (e.g., in NaCl).
• Hydrogen bonds are weak attractions between a slightly positive hydrogen atom (in a polar covalent bond) and a slightly negative atom (like O, N, or F) in another molecule.

1. Analyze the given situation: Two water molecules are interacting. The slight positive of hydrogens in one water molecule is attracted to the slight negative of oxygen in another water molecule. This fits the definition of a hydrogen bond, as it is an intermolecular attraction between the polar parts of different water molecules. Polar covalent bonds are intramolecular (within a molecule), non - polar covalent bonds do not have the partial charges needed for this attraction, and ionic bonds involve charged ions, not partial charges in molecules.

Answer:

D. hydrogen
