Problem

Consider the following two carbonyl compounds (i) [Tc(CO)6]+[\text{Tc}(\text{CO})_6]^+ and (ii) [Nb(CO)6]−[\text{Nb}(\text{CO})_6]^- Select incorrect statement(s) for given carbonyl compounds. (1) [Tc(CO)6]+[\text{Tc}(\text{CO})_6]^+ acts as reducing agent and [Nb(CO)6]−[\text{Nb}(\text{CO})_6]^- acts as oxidizing agent (2) [Nb(CO)6]−[\text{Nb}(\text{CO})_6]^- acts as reducing agent and [Tc(CO)6]+[\text{Tc}(\text{CO})_6]^+ acts as oxidizing agent (3) "Nb—C" bond order in [Nb(CO)6]−[\text{Nb}(\text{CO})_6]^- is greater than "Tc—C" bond order in [Tc(CO)6]+[\text{Tc}(\text{CO})_6]^+ (4) "CO" bond order is greater in [Nb(CO)6]−[\text{Nb}(\text{CO})_6]^- than in [Tc(CO)6]+[\text{Tc}(\text{CO})_6]^+
