Question

Ionic compounds exist in state at room temperature because they have strong of attraction.

• A. solid
• B. liquid
• C. electrostatic forces
• D. van der Waals forces

Answer 1

Answer: (A), (C)

The correct options are
A solid
C electrostatic forces

Ionic compounds have strong electrostatic forces of attraction between the ions and form a lattice of ions. Thus, they exist as solids at room temperature. A high amount of energy is required to overcome these forces and move the ions apart. That is why they usually have high melting points.
