120) When Cl₂ is passed through hot conc. NaOH, salts A and B are formed, which are separated by fractional crystallization. When B is treated with a calculated amount of KCl, a substance C is produced. When C is gently heated, it disproportionates to give D and E. When E is heated with conc. H₂SO₄, the strongest Bronsted acid F is formed, which is isoelectronic with H₂SO₄. Identify F.

HClO₂

HClO₃

HClO₄

HCl

Answer is:

HCl

121) PCl₃ and PCl₅ both exist; NCl₃ exists, but NCl₅ does not. This is due to:
