The correct statement(s) about Cr2+ and Mn3+ is(are) [Atomic numbers of Cr = 24 and Mn = 25] (A) Cr2+ is a reducing agent (B) Mn3+ is an oxidizing agent (C) Both Cr2+ and Mn3+ exhibit d4 electronic configuration (D) When Cr2+ is used as a reducing agent, the chromium ion attains d5 electronic configuration

Answer»

(A) Cr2+ is a reducing agent 

(B) Mn3+ is an oxidizing agent 

(C) Both Cr2+ and Mn3+ exhibit d4 electronic configuration 

(1) Cr2+ is a reducing agent because Cr3+ is more stable. 

(2) Mn3+ is an oxidizing agent because Mn2+ is more stable. 

(3) Cr2+ and Mn3+ exhibit d4 electronic configuration.
