Which among the following is colored?
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
CuCl has the copper in +1 oxidation state. It has the ten electrons in d-orbital. All the electrons are paired. So, it is not coloured. ScCl3 has the Sc3+. It has the d0 configuration. It has all paired electrons. So, it has no colour. CuCl2 has the Cu2+. It has the d9…
