Q53 / 180 · KCET 2021 · Chemistry
The IUPAC name of $\left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_{5}\left(\mathrm{CO}_{3}\right)\right] \mathrm{Cl}$ is
- Correct answerApentaamminecarbonatocobalt (III) chloride
- Bcarbonatopentamminecobalt (III) chloride
- Cpentaamminecarbonatocobaltate (III) chloride
- Dpentaammine cobalt (III) carbonate chloride
Solution
$\left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_{5}\left(\mathrm{CO}_{3}\right)\right] \mathrm{Cl}$
Oxidation state of $\operatorname{Co}(x)$ can be calculated
$\begin{array}{ll}
& x+0+0-3=0 \\
\therefore \quad & x=3
\end{array}$
$\therefore$ The IUPAC name is pentaamminecarbonatocabolt(III)chloride.
Hence, the correct answer is option: 'A'.
