Question

The ion which is not tetrahedral in shape is?

• A. $B{F}_4^{-}$
• B. $N{H}_4^{+}$
• C. $\left[Cu\right(N{H}_3{)}_4{]}^{2+}$
• D. $NiC{l}_4^{2-}$

Answer 1

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

$\left[Cu\right(N{H}_3{)}_4{]}^{2+}$ is square planar
Hybridazation state of $C{u}^{+2}$ is $ds{p}^2$
