1. During the electrolysis of aqueous solution of NaCl with inert electrodes at the cathode instead of Na₄⁺ reduction of H⁺ takes place because:

Compared to H₄⁺ standard reduction potential of Na₄⁺ is higher

Sodium metal is inactive metal

Standard oxidation potential of H⁺ is very high

Reduction potential of Na⁺ is very less
