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

Solution

$$
\text { }\left[\mathrm{Cu}\left(\mathrm{NH}_{3}ight)_{4}ight]^{2+} \text { has square planar structure and is paramagnetic. }
$$ /
