####24. Two complexes
(2019 Main, 9 Jan I)
(a)
(b) both absorb energies corresponding to their complementary colours
(c)
(d) both are paramagnetic with three unpaired electrons
Show Answer
Answer:
Correct Answer: 24. (d)
Solution:
- ’
’ absorbs yellow light of less energy and emits violet light of high energy (complementary colour) because is a weak field ligand. But in case of ’ ‘, due to presence of strong field ligand , it absorbs high energy violet light and emits low energy complementary yellow colour.
Both the complexes contain three unpaired electrons. Therefore, both are paramagnetic.
