Vedclass · Answer

(D) Step $1$: Manganese can exhibit a maximum oxidation state of $+7$ by using all its valence electrons $(3d^5 4s^2)$.Step $2$: Oxygen has the unique ability to form multiple bonds (specifically $p\pi - d\pi$ multiple bonds) with transition metals, which stabilizes the higher oxidation states of the metal.Step $3$: Fluorine, being highly electronegative and small, can only form single covalent bonds $(Mn-F)$. It cannot form multiple bonds with manganese.Step $4$: Therefore, oxygen can satisfy the high valency of manganese in $Mn_2O_7$ through multiple bonding, whereas fluorine is restricted to $MnF_4$.

The highest oxidation state of manganese in fluorides is $+4$ $(MnF_4)$, but the highest oxidation state in oxides is $+7$ $(Mn_2O_7)$, because

Which of the following represents the correct chemical reactions related to iron and its compounds?

In which of the following, ions are correctly arranged in the increasing order of oxidizing power?

$(a)$ Transition metals can act as catalysts because they can change their oxidation state. How does $Fe(III)$ catalyze the reaction between iodide and persulphate ions?
$(b)$ Mention any three processes where transition metals act as catalysts.

Assertion : Transition metals are good catalysts.
Reason : $V_2O_5$ or $Pt$ is used in the preparation of $H_2SO_4$ by contact process.

Assertion : $PbI_4, BiCl_5, FeI_3, CuI_2$ do not exist. Reason : Higher oxidation states of metal ions are strong oxidising agents which give redox reactions with the iodide ion.
