Question

Which of the following statements are correct?
(i) The maximum oxidation state of $Mn$ with the oxygen is $+VII$ while with fluorine is $+ IV$.
(ii) Fluorine is more oxidizing in nature than oxygen.
(iii) Fluorine exhibit an oxidation state of $-1$.
(iv) Seven fluorine cannot be accommodated around $Mn$.

• A. (i),(ii) and(iii)
• B. (ii), (iii) and (iv)
• C. (i) and (iv)
• D. (i), (ii), (iii) and (iv)

Answer 1

Answer: (D)

The ability of oxygen to stabilise high oxidation states exceeds that of fluorine. Thus, the highest fluoride with $Mn$ is $MnF _4$, whereas the highest oxide is $Mn _2 O _7$. Also, it is hard to accommodate 7 fluorine atoms around $Mn$.
