Single correct option
Which of the following compounds does NOT conduct electricity in the molten state?
- A. CCl₄
- B. NaCl
- C. MgCl₂
- D. KCl
Show answer and solution
Answer: (A) CCl₄
Conduction in the molten state needs mobile ions. NaCl, KCl and MgCl₂ are ionic and break up into ions on melting, so they conduct. CCl₄ is a covalent molecular compound with no ions, so it does not conduct as a liquid either.
