AIIMS 2019 Chemistry Oxidizing Agents MCQ Question

Type: MCQ-conceptual-Medium-Class 11

Which of the following complex is optically inactive

A

[RhCl(CO)(PPh3)(NH3)][\text{RhCl}(\text{CO})(\text{PPh}_3)(\text{NH}_3)]

B

[Fe(C2O4)3]3[\text{Fe}(\text{C}_2\text{O}_4)_3]^{3-}

C

[Fe(en)2Cl2][\text{Fe}(\text{en})_2\text{Cl}_2]

D

[Pd(en)2Cl2][\text{Pd}(\text{en})_2\text{Cl}_2]

Correct Answer

Option A

Detailed Explanation

In the reaction between I₂O₅ and CO, iodine (I₂) is produced as a result of the reduction of I₂O₅, which acts as a strong oxidizing agent. The oxidation of carbon monoxide (CO) to carbon dioxide (CO₂) occurs simultaneously, but the primary product of the reduction of I₂O₅ is iodine. Other options are incorrect because carbon dioxide (CO₂) is a product of the reaction, while carbon monoxide (CO) is the reactant being oxidized, and oxygen is not produced in this specific reaction.
