Which of the following will form an octahedral complex?

Ad4 (low spin)
Bd8 (high spin)
Cd5 (low spin)
Correct Answer
DAll of these

Solution

An octahedral complex will be formed by $$\displaystyle d^5$$ low spin. Out of 5 d orbitals, 3 will contains electrons and 2 will be empty. These 2 empty d orbitals can undergo $$\displaystyle sp^3d^2$$ hybridisation (or $$\displaystyle d^2sp^3$$ hybridisation) to form octahedral complex.
