Chemistry - Coordination Chemistry Question with Solution | TestHub
A complex salt 'A' gives deep blue ppt. of 'B' on the reaction with aqueous solution of . 'A' also reacts with concentrate to give a gas 'G', Which can combine with Hemoglobin in red blood cells. The select INCORRECT information(s).
Options:(select one or more)
Answer:
Solution:
Identification: Complex salt 'A' is K₄[Fe(CN)₆], the deep blue precipitate 'B' is Prussian blue (Fe₄[Fe(CN)₆]₃), and gas 'G' is carbon monoxide (CO).
Statement B is incorrect: The dipole moment of CO points from the more electronegative oxygen atom to the less electronegative carbon atom (C O) due to coordinate bonding.
Statement D is incorrect: While 'A' is diamagnetic, compound 'B' contains external Fe³⁺ ions with unpaired electrons, making it highly paramagnetic rather than diamagnetic.
Statements A and C are correct: Both show linkage isomerism via CN⁻, and the average oxidation state of Fe in 'B' is (which is ) via a non-redox precipitation.
