1.Which of the following order is correct for the IR vibrational frequency (νCO\nu_{\text{CO}}νCO) of CO?a.[Co(CO)4]−<[Ni(CO)4][\text{Co(CO)}_4]^- < [\text{Ni(CO)}_4][Co(CO)4]−<[Ni(CO)4]b.[Co(CO)4]−>[Ni(CO)4][\text{Co(CO)}_4]^- > [\text{Ni(CO)}_4][Co(CO)4]−>[Ni(CO)4]c.[Co(CO)4]−<[Ni(CO)4][\text{Co(CO)}_4]^- < [\text{Ni(CO)}_4][Co(CO)4]−<[Ni(CO)4] (reverse)d.[Co(CO)4]−=[Ni(CO)4][\text{Co(CO)}_4]^- = [\text{Ni(CO)}_4][Co(CO)4]−=[Ni(CO)4]Login to continueOnly logged in users canattempt or see the solution.
