Q. The lowest energy d → d transition of the complexes follow the order
(A) [Cr(H2O)6]3+ < [Cr(NH3)6]3+ < [Cr(CN)6]3–
(B) [Cr(CN)6]3– < [Cr(NH3)6]3+ < [Cr(H2O)6]3+
(C) [Cr(CN)6]3– < [Cr(H2O)6]3+ < [Cr(NH3)6]3+
(D) [Cr(NH3)6]3+ < [Cr(CN)6]3– < [Cr(H2O)6]3+
Ans: [Cr(H2O)6]3+ < [Cr(NH3)6]3+ < [Cr(CN)6]3–
