Question

What is the spin only magnetic moment of the d- block metal present in the Zieglar-Natta catalyst?

Answer 1

Zieglar-Natta catalyst is:($TiC{l}_4+Al(C{H}_{2}C{H}_3{)}_3$)
Here $Ti$ exists in the +4 oxidation state. So, the electronic configuration of $T{i}^{4+}$ will be $1s^{2}2s^{2}2p^{6}3s^{2}3p^6$. Since there are no unpaired electrons in $T{i}^{4+}$, the spin only magnetic moment of $Ti$ in Zieglar-Natta catalyst is 0.
