Option A: [MnO4]–, CrO2CI2
Only Co+ because of the presence of unpaired electrons in d-orbitals show d-d transition and, hence it is coloured.
CUET Exam Question No: 7
Which among the following will be named as dibromidobis (ethylenediammine) chromium (III) bromide ?
Option A : [Cr](en)3]Br3
Option B : [Cr(en)2Br2]Br
Option C : [Cr(en)Br4]–
Option D : [Cr(en)Br2]Br
Show/Hide Answer Key
Option B: [Cr(en)2Br2]Br
Two Br, two (en) and one Cr are parts of the complex.
Charge on the complex is +1.
2 (Br) = -2
2 (en) = 0
1 (Cr) = +3
Thus, complex ion is[Cr(en)2 Br2]+
Since, anion is bromide, thus complex dibromido bis (ethylenediamine) chromium (III) bromide is written as [Cr(en)2Br2]Br
