Which of the following statement is not true for the reaction given below?…
$\left[\mathrm{Cu}\left(\mathrm{H}_{2} \mathrm{O}ight)_{4}ight]^{2+}+4 \mathrm{NH}_{3} ightleftharpoons \left[\mathrm{Cu}\left(\mathrm{NH}_{3}ight)_{4}ight]^{2+}+4 \mathrm{H}_{2} \mathrm{O}$
- It is a ligand substitution reaction
- $\mathrm{NH}_{3}$ is relatively strong field ligand while $\mathrm{H}_{2} \mathrm{O}$ is a weak field ligand
- During the reaction, there is a change in colour form light blue to dark blue
- $\left[\mathrm{Cu}\left(\mathrm{NH}_{3}ight)_{4}ight]^{2+}$ has tetrahedral structure and is paramagnetic
Solution
\text { }\left[\mathrm{Cu}\left(\mathrm{NH}_{3}ight)_{4}ight]^{2+} \text { has square planar structure and is paramagnetic. }
