Which element from following forms colourless compounds in \(+2\) oxidation state?
- A \(\operatorname{Co}(\mathrm{Z}=27)\)
- B \(\operatorname{Zn}(\mathrm{Z}=30)\)
- C \(\operatorname{Cu}(Z=29)\)
- D \(\mathrm{Mn}(\mathrm{Z}=25)\)
Answer & Solution
Correct Answer
(B) \(\operatorname{Zn}(\mathrm{Z}=30)\)
Step-by-step Solution
Detailed explanation
\(\operatorname{Zn}(Z=30)\)
\(\mathrm{Zn}^{2+} \longrightarrow 3 \mathrm{~d}^{10}\) (No unpaired d-electron)
\(\therefore \mathrm{Zn}\) forms colourless compounds in \(+2\) oxidation state.
\(\mathrm{Zn}^{2+} \longrightarrow 3 \mathrm{~d}^{10}\) (No unpaired d-electron)
\(\therefore \mathrm{Zn}\) forms colourless compounds in \(+2\) oxidation state.
