What are typical characteristics of ionic compounds?

• A. High melting points and flexibility
• B. Brittleness and electrical conductivity when dissolved
• C. Poor solubility in water and low conductivity
• D. Low melting points and malleability

Answer: (B)

Ionic compounds exhibit specific characteristics that arise from their unique structures and bonding. One of the most notable features is their brittleness; when stress is applied to an ionic crystal, the alignment of like-charged ions can lead to repulsion, causing the crystal to shatter. Additionally, ionic compounds conduct electricity when they are dissolved in water or melted. This is because the ionic bonds break, allowing the ions to move freely in solution, facilitating the flow of electrical current. In solid form, the ions are held in a rigid lattice structure, which does not allow for electrical conductivity. These features differentiate ionic compounds from other types of materials, such as covalent compounds or metals, which may possess different thermal and electrical properties. The combination of brittleness and the ability to conduct electricity in solution clearly aligns with the characteristics of ionic compounds, making this answer the most appropriate response to the question regarding typical characteristics.
