Question

Match the following organometallic compounds (List-I) with their Characteristics (List-II)\[\begin{array}{|c|c|} \hline \textbf{List-I (Organometallic Compounds)} & \textbf{List-II (Characteristics)} \\ \hline \text{(A) Fe(C$_5$H$_5$)$_2$} & \text{(III) Fluxionality} \\ \hline \text{(B) K$^+$[PtCl$_3$(C$_2$H$_4$)]} & \text{(I) dsp$^2$ hybridization} \\ \hline \text{(C) Mg(CH$_3$)$_2$} & \text{(IV) Polymeric in nature} \\ \hline \text{(D) (CH$_3$)$_2$AlF$_4$} & \text{(II) Tetramer structure} \\ \hline \end{array}\]

• (A) - (I), (B) - (III), (C) - (II), (D) - (IV)
• (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
• (A) - (III), (B) - (I), (C) - (IV), (D) - (II)
• (A) - (II), (B) - (IV), (C) - (I), (D) - (III)

Hint:

Organometallic compounds can have distinct properties such as fluxionality, hybridization types, and structural characteristics like polymeric and tetramer structures.

Answer 1

The Correct Option is B

Step 1: Understanding the Organometallic Compounds and their Characteristics.
- (A) Fe(C\(_5\)H\(_5\))\(_2\): This is a ferrocene compound, where iron is sandwiched between two cyclopentadienyl anions. The metal in this complex undergoes dsp\(^2\) hybridization. - (B) K\(^+\)[PtCl\(_3\)(C\(_2\)H\(_4\))]: This complex has a tetramer structure, which means it is composed of four monomeric units. - (C) Mg(CH\(_3\))\(_2\): This is an organomagnesium compound, and such compounds exhibit fluxionality, where the ligands may interchange positions. - (D) (CH\(_3\))\(_2\)AlF\(_4\): This complex is polymeric in nature due to the bonding between the metal center and the ligands forming extended chains or networks.

Step 2: Conclusion.
Thus, the correct matching is: - (A) - (I): Fe(C\(_5\)H\(_5\))\(_2\) undergoes dsp\(^2\) hybridization. - (B) - (II): K\(^+\)[PtCl\(_3\)(C\(_2\)H\(_4\))] has a tetramer structure. - (C) - (III): Mg(CH\(_3\))\(_2\) exhibits fluxionality. - (D) - (IV): (CH\(_3\))\(_2\)AlF\(_4\) is polymeric in nature. Therefore, the correct answer is option (2).
