Q2. The value of molar conductivity of HCl is greater than that of NaCl at a particular temperature because 

   (1) Molecular mass of HCl is less than that of NaCl.    (2) Velocity of H+ ions is more then that of Na+ ions

   (3) HCl is strongly acidic                                               (4) Ionisation of HCl is larger than that NaCl.

Option (2) is correct
H+ ion is smaller than Na+ ion , due to which it moves faster in the solution of the electrolytes .?
thatswhy the molar conductivity of hcl is higher than that of nacl .?
