Which of the following do not exists ?
Options:(select one or more)
Answer:
A, B, C
Solution:
SH₆ → Sulphur does not form a stable hexahydride because such a high oxidation state hydride is not possible.
HFO₄ → Fluorine does not show positive oxidation states, so oxyacid HFO₄ cannot exist.
FeI₃ → Fe³⁺ oxidises I⁻ to I₂, so FeI₃ is not stable.
HClO₃ → Chloric acid exists as a stable oxyacid.
