According to Crystal-Field Theory, the electronic configuration of complex compound [A] is $t_{2g}^4 e_g^2$ and that of complex compound [B] is $t_{2g}^6 e_g^0$.
Which of the two complex compounds, [A] or [B], is a low spin complex?
Answer
Answer
AIComplex [B] ($t_{2g}^6 e_g^0$) is the low spin complex: all six $d$ electrons are paired in the lower $t_{2g}$ set and none occupy the $e_g$ orbitals.
