Assertion : The highest manganese fluroide is `MnF_(4)` and the highest oxide is `Mn_(2) O_(7)`.
Reason : In `Mn_(2) O_(7)`, each `Mn` is tetrahedrally surrounded by `O's` including `Mn-O-Mn` bridge.

A

If both assetion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are ture but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
B
Both assertion and reason are correct and reason is not the correct explanation of assertion.
Manganese with fluorine form `MnF_(4)` in highest oxidation state because of high electronegatively of fluorne.
Oxygen forms multiple bonds to metals which expalin its superiority over fluorine.

Higher oxidation state of manganese in fluoride is +4 (MnF_(4)) but highest oxidation state in oxides is +7(Mn_(2)O_(7)) because

MnF_(7) is not stable while Mn_(2)O_(7) is stable.

The highest oxidation state of Mn is shown by

(a) Give reasons for the following : (i) Mn^(3+) is a good oxidising agent. (ii) E(M^(2+)//M)^(@) values are not regular for first row transition metals (3d series). (iii) Although 'F' is more electronegative then 'O', the highest Mn fluoride is MnF_(4) whereas the highest oxide is Mn_(2)O_(7) . Complete the following equations : (ii) 2 CrO_(4)^(2-)+2H^(+)rarr (ii) KMnO_(4)overset("heat")rarr
