Which amongst the following does not conduct electricity ? Why? (a)CH3COOH (b)C3H7OH (c)HCOOH (d)Nacl(aq)
Dear Student,
(a),(b) and (c) are non -conductors of electricity because for the conduction of electricity free ions are needed but these substances do not ionize (or if they do only to a very small extent) hence they do not conduct electricity. If these substances are taken in aqueous solution, then the conduction of electricity is possible bacause degree of ionization increases on addition of water.
Regards!
