Question

Match List I with List II for the oxidation state of central atoms:

List I	List II
(A) Cr2O72−	(I) +3
(B) MnO4−	(II) +5
(C) VO3−	(III) +7
(D) FeF63−	(IV) +6

Choose the correct answer from the options given below:

• A. (A)- (I), (B)- (II), (C)- (III), (D)- (IV)
• B. (A)- (IV), (B)- (III), (C)- (II), (D)- (I)
• C. (A)- (I), (B)- (II), (C)- (IV), (D)- (III)
• D. (A)- (IV), (B)- (I), (C)- (III), (D)- (II)

Answer 1

The Correct Option is B

The oxidation states for each compound are as follows:

• Cr₂O₇²⁻: Chromium (Cr) is in the +6 oxidation state.
• MnO₄⁻: Manganese (Mn) is in the +7 oxidation state.
• VO₃⁻: Vanadium (V) is in the +5 oxidation state.
• FeF₆³⁻: Iron (Fe) is in the +3 oxidation state.
