Q. The reaction of equimolar quantities of Fe(CO)5 and OH^– gives a complex species X which on further reaction with MnO2 gives species Y. X and Y, respectively, are

(A) [Fe(CO)5(OH)]^– and Fe2(CO)9

(B) [Fe(CO)4]^2– and Mn2(CO)10

(C) [HFe(CO)4]^– and Fe2O3

(D) [HFe(CO)4]^– and Fe3(CO)12

Ans: [HFe(CO)4]- and Fe3(CO)12
