Q64.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 (1) Mn2+ (2) Cr3+ (3) Ni2+ (4) Ti3+
What This Question Tests
This question assesses knowledge of transition metal electronic configurations (specifically unaffected by ligand nature implies d0 or d10 or completely filled/half-filled stable configuration) and their characteristic colors in the borax bead test.
