MCQ
Which of the following is expected to form colourless complex
- A$N{i^{2 + }}$
- ✓$C{u^ + }$
- C$T{i^{3 + }}$
- D$F{e^{3 + }}$
✓
Answer
Correct option: B.
$C{u^ + }$
b
(b) In $C{u^{ + 1}}$ (cuprous ion) $d$ orbitals are completely filled so it will form colourless complex.
(b) In $C{u^{ + 1}}$ (cuprous ion) $d$ orbitals are completely filled so it will form colourless complex.
