Introduction to π-Bonded Organometallic Compounds
Organometallic compounds are characterized by the presence of carbon-metal bonds. Among them, π-bonded compounds are those where the metal interacts with π electrons of ligands, typically involving aromatic or alkene groups.
Identifying the Compounds
Let's analyze the given compounds to determine if they are π-bonded:
Conclusion
Thus, the correct options indicating π-bonded organometallic compounds are:
- A) Ferrocene
- B) [Ni(C5H5)2]
- D) Dibenzene chromium
C) Ethylmagnesium iodide is not π-bonded.
Organometallic compounds are characterized by the presence of carbon-metal bonds. Among them, π-bonded compounds are those where the metal interacts with π electrons of ligands, typically involving aromatic or alkene groups.
Identifying the Compounds
Let's analyze the given compounds to determine if they are π-bonded:
- Ferrocene (A):
- Ferrocene consists of a central iron atom sandwiched between two cyclopentadienyl anions (C5H5-).
- The interaction between the iron and the π electrons of the cyclopentadienyl rings classifies it as a π-bonded organometallic compound. - [Ni(C5H5)2] (B):
- This compound features nickel coordinating with two cyclopentadienyl anions, similar to ferrocene.
- The nickel interacts with the π electrons of the ligands, making it a π-bonded organometallic compound. - Ethylmagnesium iodide (C):
- This compound is an organometallic reagent but does not have π-bonding.
- It features an alkyl (ethyl) and a metal (magnesium) connected by a σ bond, rather than π interactions. - Dibenzene chromium (D):
- Here, chromium is bonded to two benzene rings.
- The bonding involves π interactions between the chromium and the π electrons of the benzene, qualifying it as a π-bonded organometallic compound.
Conclusion
Thus, the correct options indicating π-bonded organometallic compounds are:
- A) Ferrocene
- B) [Ni(C5H5)2]
- D) Dibenzene chromium
C) Ethylmagnesium iodide is not π-bonded.
