Question

which of the following does not conduct electric current and why? molten NaCl, AgNO3,solid pb and methanol.​

Answer 1

Answer:

solid lead will not conduct electricity as there be no formation of ions

Answer 2

Methanol

This is because of the fact that Methanol is a carbon compound formed by covalent bonds and thus there are no free ions to conduct electricity.

molten NaCl and AgNO3 on the other hand are ionic compounds and in the molten state, dissociate into ions which conduct electricity.

Solid Pb also has free ions in it, since it is a metal and thus it conducts electricity.
