Verified step by step guidance

1. Identify the characteristics of a nonelectrolyte: Nonelectrolytes do not dissociate into ions in solution and therefore do not conduct electricity.
2. Examine the provided diagram: Look for molecular representations that do not show dissociation into ions.
3. Consider the molecular structure: A nonelectrolyte will typically be a covalent compound that remains intact in solution.
4. Analyze the image: Determine if the diagram shows molecules that are not separated into ions, indicating a nonelectrolyte.
5. Select the appropriate diagram: Choose the diagram that best represents a solution where the solute remains as whole molecules, not ions.

Key Concepts

Solute and Solvent

In a solution, the solute is the substance that is dissolved, while the solvent is the medium in which the solute dissolves. For example, in a saltwater solution, salt is the solute and water is the solvent. Understanding the roles of solutes and solvents is crucial for analyzing how solutions form and behave.

Nonelectrolyte

A nonelectrolyte is a substance that does not dissociate into ions when dissolved in a solvent, meaning it does not conduct electricity. Common examples include sugar and alcohol. Recognizing whether a solute is a nonelectrolyte helps in predicting the properties of the solution, such as its conductivity and boiling point.

Molecular Representation

Molecular representation involves using diagrams or models to illustrate the structure and interactions of molecules in a solution. The blue and red spheres in the provided image likely represent different types of molecules, helping visualize how solutes interact with solvents. This concept is essential for understanding the physical and chemical properties of solutions.
