Single correct option
Consider the following statements about ionic compounds:
1. They generally have high melting points.
2. They conduct electricity in the solid state.
Which of the statements given above is/are correct?
1. They generally have high melting points.
2. They conduct electricity in the solid state.
Which of the statements given above is/are correct?
- A. 1 only
- B. 2 only
- C. Both 1 and 2
- D. Neither 1 nor 2
Show answer and solution
Answer: (A) 1 only
Strong electrostatic forces between oppositely charged ions give high melting and boiling points. In the solid state, the ions are fixed in the lattice and cannot move, so no conduction occurs; they conduct only when molten or dissolved in water. Hence only statement 1 is correct.
