Question

slightly negative end (a) slightly positive ends molecule in which opposite ends have opposite electric charges solution hydrogen bond cohesion polar molecule

Explanation:

To solve this, we analyze each option:

• "solution" refers to a homogeneous mixture, not matching the description.
• "hydrogen bond" is an intermolecular force, not a molecule with opposite charges.
• "cohesion" is the attraction between similar molecules, not related to molecular charge distribution.
• "polar molecule" is defined as a molecule with opposite ends (poles) having opposite electric charges, which matches the given description.

Answer:

D. polar molecule (assuming the options are labeled A to D with A: solution, B: hydrogen bond, C: cohesion, D: polar molecule)
