The final products of the reaction of carbonyl metalates $\mathrm{[V(CO)_6]^{-}}$ and $\mathrm{[Co(CO)_4]^{-}}$ with $\mathrm{H_3PO_4}$ respectively, are
(a)$\mathrm{V(CO)_6}$ and $\mathrm{HCo(CO)_4}$
(b)$\mathrm{HV(CO)_6}$ and $\mathrm{Co_2(CO)_8}$
(c)$\mathrm{[H_2V(CO)_6]^{+}}$ and $\mathrm{HCo(CO)_4}$
(d)$\mathrm{V(CO)_6}$ and $\mathrm{Co_2(CO)_8}$
Answer
Answer (as printed): A
Explanation
$[\mathrm{V(CO)_6}] \rightarrow [\mathrm{V(CO)_6}]$ (in presence of $\mathrm{H_3PO_4}$)$[\mathrm{Co(CO)_4}] \rightarrow [\mathrm{HCo(CO)_4}]$ (in presence of $\mathrm{H_3PO_4}$)
