Question

The correct order of following 3d metal oxides, according to their oxidation number is: (a) (b) (c) (d) (e)

(A) (d) > (a) > (b) > (c) > (e)
(B) (a) > (c) > (d) > (b) > (e)
(C) (a) > (d) > (c) > (b) > (e)
(D) (c) > (a) > (d) > (e) > (b)

Prashant Kotian · Accepted Answer

Correct answer: C) (A) > (D) > (C) > (B) > (E). Oxidation state of O is –2 in all these compounds. (a) - Cr = +6 (b) - Fe = +3 (c) - Mn = +4 (d) - V = +5 (e) - Cu = +1
