Coordination Compounds

The pair in which both the species have the same magnetic moment (spin only) is:

Number of complexes which will exhibit synergic bonding amongst $\left[Cr{\left(CO\right)}_6\right],\left[Mn{\left(CO\right)}_5\right]$ <!-- [if gte mso 9]><xml> </xml><![endif]--> and $\left[M{n}_2{\left(CO\right)}_{10}\right]$ <!-- [if gte mso 9]><xml> </xml><![endif]--> is_______________.

Given below are two statements:

Statement I : ${\left[Ni{\left(CN\right)}_4\right]}^{2-}$ <!-- [if gte mso 9]><xml> </xml><![endif]--> is square planar and diamagnetic complex, with dsp² hybridizatin for Ni but $\left[Ni{\left(CO\right)}_4\right]$ <!-- [if gte mso 9]><xml> </xml><![endif]--> is tetrahedral, paramagnetic and with sp³ hybridization for Ni.

Statement II : ${\left[NiC{l}_4\right]}^{2-}and\left[Ni{\left(CO\right)}_4\right]$ <!-- [if gte mso 9]><xml> </xml><![endif]--> both have same d-electron configuration have same geometry and are paramagnetic.

In light the above statements, choose the correct answer from the options given below

 ${\left[Fe{\left(CN\right)}_6\right]}^{3-}$ should be an inner orbital complex. Ignoring the pairing energy, the value of crystal field stabilization energy for this complex is (-) _________ ${\Delta }_0.$ (Nearest integer)

The Crystal Field Stabilization Energy (CFSE) of $\left[{\mathrm{C}\mathrm{o}\mathrm{F}}_3{\left({\mathrm{H}}_2\mathrm{O}\right)}_3\right]\left({\mathrm{\Delta }}_0<\mathrm{P}\right)$  is :

Choose the correct answer from the options given below

Assertion: [Fe(CN)₆]^3- ion shows magnetic moment corresponding to two unpaired electrons.       

Reason: Because it has d²sp³ type hybridisation.

Assertion: Complexes of MX₆ and MX₅L type (X and L are unidentate) do not show geometrical   isomerism.

Reason: Geometrical isomerism is not shown by complexes of coordination number 6.

Assertion: Linkage isomerism arises in coordination compounds containing ambidentate ligand.                      

Reason: Ambidentate ligand has two different donor atoms.

Assertion : [Cr(H2O)6]Cl2 and [Fe(H2O)6]Cl2 are reducing in nature. 

 Reason: Unpaired electrons are present in their d-orbitals.
