Question
Which pure substance will not conduct electricity?
Answer: C
💡 Solution & Explanation
Molten NaCl and KOH are ionic liquids with free-moving ions. Liquid Hg is a metal with free delocalized electrons. Liquefied HCl is a covalent molecular substance. Pure liquid HCl does not undergo significant auto-ionization and lacks free charge carriers, meaning it will not conduct electricity. Therefore, correct answer is C.
