Question

As compared to covalent compounds, electrovalent compounds generally have:

• A. low melting points and low boilings points
• B. low melting points and high boiling points
• C. high melting points and low boiling points
• D. high melting points and high boiling points

Answer 1

The correct option is D high melting points and high boiling points

Ionic compounds have high melting and boiling point depending on the charge of the ions. The higher the charges, the stronger are the cohesive forces and higher is the melting and boiling point.
