JEE Mains · Chemistry · STD 12 - 5. Co-ordination chemistry
Given below are two statements :
Statement - I Hybridisation, shape and spin only magnetic moment of \( K_{3}[Co(CO_{3})_{3}] \) is \( sp^{3}d^{2} \), octahedral and 4.9 BM respectively.
Statement - II Geometry, hybridisation and spin only magnetic moment values (BM) of the ions \( [Ni(CN)_{4}]^{2-} \), \( [MnBr_{4}]^{2-} \) and \( [CoF_{6}]^{3-} \) respectively are square planar, tetrahedral, octahedral: \( dsp^{2} \), \( sp^{3} \), \( sp^{3}d^{2} \) and 0, 5.9, 4.9.
In the light of the above statements, choose the correct answer from the options given below
- A Both statement - I and statement - II are false
- B Statement I is false but statement - II is true
- C Both statement - I and statement - II are true
- D Statement - I is true but statement - II is false
Answer & Solution
Correct Answer
(C) Both statement - I and statement - II are true
Step-by-step Solution
Detailed explanation
In \( K_{3}[Co(CO_{3})_{3}] \Rightarrow sp^{3}d^{2} \) hybridized, octahedral \( \Rightarrow 4 \) unpaired electron \( \Rightarrow 4.9~B.M. \) \( [Ni(CN)_{4}]^{2-} \)\( \Rightarrow \) \( dsp^{2} \) hybridized, square planar \( \Rightarrow 0 \) unpaired electron…
