Question

Hybridisation of $\left[ Ni \left( NH _{3}\right)_{6}\right]^{2+}$ and $\left[ Zn \left( NH _{3}\right)_{6}\right]^{2+}$ are

• A. Both $d ^{2} sp ^{3}$
• B. Both $sp ^{3} d^{2}$
• C. $d ^{2} sp ^{3}$ and $sp ^{3} d ^{2}$ respectively
• D. ${sp}^{3} d^{2}$ and $d^{2} s p^{3}$ respectively

Answer 1

Answer: (B)

$\left[ Ni \left( NH _{3}\right)_{6}\right]^{2+}$ and $\left[ Zn \left( NH _{3}\right)_{6}\right]^{2+}$ Both $sp ^{3} d ^{2}$ hybridization. It contains two and zero unpaired electrons respectively.
