Q.
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.
Column I (Compound)
Column II (Oxidation state of $Co$)
A.
$\left[Co\left(NCS\right)\left(NH_{3}\right)_{5}\right]\left(SO_{3}\right)$
1.
$+ 4$
B.
$\left[Co\left(NH_{3}\right)_{4}Cl_{2}\right]SO_{4}$
2.
$0$
C.
$Na_{4}\left[Co\left(S_{2}O_{3}\right)_{3}\right]$
3.
$+ 1$
D.
$\left[Co\left(CO\right)_{8}\right]$
4.
$+ 2$
5.
$+ 3$
Code:
| Column I (Compound) | Column II (Oxidation state of $Co$) | ||
|---|---|---|---|
| A. | $\left[Co\left(NCS\right)\left(NH_{3}\right)_{5}\right]\left(SO_{3}\right)$ | 1. | $+ 4$ |
| B. | $\left[Co\left(NH_{3}\right)_{4}Cl_{2}\right]SO_{4}$ | 2. | $0$ |
| C. | $Na_{4}\left[Co\left(S_{2}O_{3}\right)_{3}\right]$ | 3. | $+ 1$ |
| D. | $\left[Co\left(CO\right)_{8}\right]$ | 4. | $+ 2$ |
| 5. | $+ 3$ | ||
