Which of the following system in an octahedral complex has maximum unpaired electrons?
1 \(\mathrm{d}^9\) (high spin)
2 \(\mathrm{d}^6\) (low spin)
3 \(\mathrm{d}^4\) (low spin)
4 \(\mathrm{d}^7\) (high spin)
Explanation:
(d)\(\mathrm{d}^7\) (high spin) \(=\)
\(\mathrm{d}^9(\) high spin \()=\)
\(\mathrm{d}^4(\) low spin \()=\)
\(d^6(\) low spin \()=\)
\(\mathrm{n}=\) number of unpaired electrons
Hence \(d^7\) has maximum number of unpaired electrons.
