Q. Which of the following shell, form an outer octahedral complex?
A) $d^{4}$
B) $d^{8}$
C) $d^{6}$
D) None of these
Explanation
(b)
$d^{4}$: Forms outer complex in high spin and forms inner complex in low spin. It cannot form octahedral complex.
$d^{6}$ : In low spin it forms inner octahedral complex and in high spin forms outer octahedral complex.
$d^{8}$ : Forms only outer spin octahedral complex.
