Vedclass · Answer

(A) Outer orbital hybridization involves the use of outer $d$-orbitals (i.e.,$nd$ orbitals) for hybridization,typically $sp^3d^2$.In $[Zn(NH_3)_6]^{2+}$,the oxidation state of $Zn$ is $+2$. The electronic configuration of $Zn^{2+}$ is $[Ar] 3d^{10}$.Since the $3d$ subshell is completely filled,the $NH_3$ ligands must occupy the $4s$,$4p$,and $4d$ orbitals to form the complex.Thus,it undergoes $sp^3d^2$ hybridization,which is an outer orbital complex.In contrast,$[Co(NH_3)_6]^{3+}$,$[Cr(NH_3)_6]^{3+}$,and $[V(NH_3)_6]^{3+}$ involve inner $d$-orbitals $(3d)$ for hybridization ($d^2sp^3$ hybridization).
