MCQ
Colour in transition metal compounds is attributed to:
- ASmall size of metal ions.
- BAbsorption of light in UV region.
- CComplete (ns) subshell.
- DIncomplete (n−1)d subshell.
✓
Answer
- Incomplete (n−1)d subshell.
Explanation:
Any compound or ion showing colour is due to presence of unpaired electron. Transition metal compounds have incomplete (n-1)d sub shell and because of that they have unpaired electron and thus they show colour.
