    Which of the following statement is not true for the reaction given below? \[{{\left[ Cu\,{{({{H}_{2}}O)}_{4}} \right]}^{2+}}+4N{{H}_{3}}\rightleftharpoons {{\left[ Cu{{(N{{H}_{3}})}_{4}} \right]}^{2+}}+4{{H}_{2}}O\]

    A) It is a ligand substitution reaction

    B) \[N{{H}_{3}}\] is relatively strong field ligand while \[{{H}_{2}}O\] is a weak field ligand

    C) During the reaction, there is a change in colour form light blue to dark blue

    D) \[{{[Cu{{(N{{H}_{3}})}_{4}}]}^{2+}}\] has tetrahedral structure and is paramagnetic

    Correct Answer: D

    Solution :

    [d] \[{{[Cu{{(N{{H}_{3}})}_{4}}]}^{2+}}\]has square planar structure and is paramagnetic.
