The molecule in which hybrid MOs involve only one d-robital of the central atom is :

The molecule in which hybrid

MOs

involve only one d-robital of the central atom is :

${Ni (CN)_{4}]}^{2 -}$
${BrF}_{5}$
${XeF}_{4}$
${[{CrF}_{6}]}^{3 -}$

Solution

Complex	Hybridisation
$(1) {[Ni (CN)_{4}]}^{2 -}$	${dsp}^{2}$
$(2) {XeF}_{4}$	${sp}^{3} d^{2}$
$(3) {[{CrF}_{6}]}^{3}$	${sp}^{3} d^{2}$
${(4) BrF}_{5}$	${sp}^{3} d^{2}$
