Which of the following statements is not...

Which of the following statements is not true of the reaction given below

(a) it is a ligand -substition reaction
(b) `NH_(3)` is a relatively strong-field ligand while `H_(2)O` is a weak field ligand
(c ) During the reaction there is a change in colour from light blue to dark blue
(d) `[Cu(NH_(3))_(4)]^(2+)` has a tetrahedral structure and is paramagnetic .

Text Solution

Verified by Experts

The correct Answer is:
d
`H_(2)O` and `NH_(3)` ligand are substituted so it is a ligand substitution reaction `NH_(3)` is powerful ligand (strong field than `H_(2)O)` and hence capable of pairing Thus `[Cu(NH_(3))_(4)]^(3+)` is no more tetrahedral it turn to be square planar complex

Give the correct of initials T or F for following statements. Use T if statements is true and F if it is false. (I) Co(III) is stabilised in presence of weak field ligands, while Co(II) is stabilised in presence of strong field ligand. ((II) Four coordinated complexes of Pd(II) and Pt(II) are diamagnetic and square planar. (III) [Ni(CN)_(4)]^(4-) ion and [Ni(CO)_(4)] are diamagnetic tetrahedral and square planar respectively.

Consider the chemical reaction: underset(("Green solution"))(Ni^(2+)(aq))+6NH_(3)(aq) hArr underset(("Blue solution"))([Ni(NH_(3))_(6)]^(2+)) (aq) When H^(o+)(aq) is added, the colour green is favoured. Use one or more of the following interpretations to answer the questions: i. Some unreacted Ni^(2+)(aq) is present in the solution at equilibrium ii. Some unreacted NH_(3)(aq) is present in the solution at equilibrium iii. The colour change indicates new equilibrium conditions with reduced [Ni(NH_(3))_(6)]^(2+)(aq) iv. The colour change indicates new equilibrium conditions with increased [Ni(NH_(3))_(6)]^(2+)(aq) . The deepening of blue colour on addition of more NH_(3)(aq) supports interpretation(s).
