Chemistry - Coordination Chemistry Question with Solution | TestHub

Question Explanation:

Select correct statement(s).

Concept:

This question is based on C.F.T.

Solution:

(1) Electronic configuration of central metal atom in both cases is $[\mathrm{Ar}]3{\mathrm{d}}^{10}4{\mathrm{s}}^{2}4{\mathrm{p}}^6$ ( 8 electrons in outermost shell and 18 valence electrons respectively).

(2) These are low spin in nature due to the presence of strong field ligand

(3) As density of electron increases on the metal, extent of Synergic bonding increases hence strengthen the metal- carbon bond

(4) As M-C bond order ↑, CO bond length ↑
