Which of the following pair of ions have same paramagnetic moment?
- A \(\mathrm{Cu}^{2+}, \mathrm{Ti}^{3+}\)
- B \(\mathrm{Mn}^{2+}, \mathrm{Cu}^{2+}\)
- C \(\mathrm{Ti}^{4+}, \mathrm{Cu}^{2+}\)
- D \(\mathrm{Ti}^{3+}, \mathrm{Ni}^{2+}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{Cu}^{2+}, \mathrm{Ti}^{3+}\)
Step-by-step Solution
Detailed explanation
\({ }_{29} \mathrm{Cu}=[\mathrm{Ar}] 3 d^{10} 4 s^1\) Both of these ions have one unpaired electron, hence these have same paramagnetic moment.
