The metal ion whose electronic configuration is not affected by the nature of the ligand and which gives a violet colour in non-luminous flame under hot condition in borax bead test is _______.
- A \(\mathrm{Mn}^{2+}\)
- B \(\mathrm{Cr}^{3+}\)
- C \(\mathrm{Ni}^{2+}\)
- D \(\mathrm{Ti}^{3+}\)
Answer & Solution
Correct Answer
(C) \(\mathrm{Ni}^{2+}\)
Step-by-step Solution
Detailed explanation
\(\mathrm{Ni}^{2+}\) gives violet colour with borax bead test in nonluminous flame under hot conditions. \(\mathrm{Ni}^{2+}\) has \(\mathrm{d}^8\) configuration which does not depend on nature of ligand present in octahedral field.…
