MCQ
Wavelength of red light is absorbed by the complex
- A$[Cu(CN)_4]^{2-}$
- ✓$[Cu(NH_3)_4]^{2+}$
- C$CuSO_4$
- D$Cu(CN)_2$
✓
Answer
Correct option: B.
$[Cu(NH_3)_4]^{2+}$
b
The compound which appears blue green, absorb red light as blue-green is complementary to red colour. Here $[Cu(NH_3)_4]^{2+}$ appears blue-green, so it absorbs red colour.
