Question

With respect to hypochlorite, chlorate and perchlorate ions, choose the correct statement(s)

• A. The hypochlorite ion is the strongest conjugate base
• B. The molecular shape of only chlorate ion is influenced by the lone pair of electrons of $Cl$
• C. The hypochlorite and chlorate ions disproportionate to give rise to identical set of ions
• D. The hypochlorite ion oxidizes the sulfite ion

Answer 1

Answer: (A), (B), (D)

The hypochlorite ion is the strongest conjugate base

Answer 2

In chlorate ion bond angle changes due to presence of lone pair on chlorine atom while hypochlorite ion is linear and perchlorate ion is tetrahedral and there is no effect of lone pair on hypochlorite ion.
(A)The hypochlorite ion is the strongest conjugate base
(B)The molecular shape of only chlorate ion is influenced by the lone pair of electrons of $Cl$
(D)The hypochlorite ion oxidizes the sulfite ion
