Question

Which of the following description of hybridisation is not correct?

• A. $[Fe{F}_6{]}^{3-},s{p}^3{d}^2$
• B. $\left[Fe\right(CN{)}_6{]}^{4-},d^2{s}^3$
• C. $\left[Cu\right(N{H}_3{)}_4{]}^{2+},s{p}^3$
• D. $\left[Ni\right(CO{)}_4],s{p}^3$

Answer 1

The correct option is C $\left[Cu\right(N{H}_3{)}_4{]}^{2+},s{p}^3$

It is square planar and has $ds{p}^2$ hybridisation.
