Match the compounds given in column-I with the oxidation state of cobalt present in it (given in column-II) and assign the correct code.
\( \mathrm{P} \)
\( \begin{array}{l}\text { Column-I } \\ \text { (Complexes) }\end{array} \)
(P) \( \left[\mathrm{Co}(\mathrm{NCS})\left(\mathrm{NH}_{3}\right)_{5}\right] \mathrm{SO}_{3} \)
(Q) \( \left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_{4} \mathrm{Cl}_{2}\right] \mathrm{SO}_{4} \)
(R) \( \mathrm{Na}_{4}\left[\mathrm{Co}\left(\mathrm{S}_{2} \mathrm{O}_{3}\right)_{3}\right] \)
(S) \( \left[\mathrm{Co}_{2}(\mathrm{CO})_{8}\right] \)
W
Codes :
(a) \( \begin{array}{llll}\mathrm{P} & \mathrm{Q} & \mathrm{R} & \mathrm{S} \\ \text { (b) } & 2 & 4 & 5\end{array} \)
(b) \( \begin{array}{lllll}4 & 3 & 2 & 1\end{array} \)
(c) \( \begin{array}{llll}5 & 1 & 4 & 2\end{array} \)
