AIIMS 2019 Chemistry Molecular Orbital Theory MCQ Question
Type: MCQ-conceptual-Medium-Class 11
The F–C bond has σ and π characteristics because of some back-bonding between d-orbital of metal and p-orbital of carbon.
Correct Answer
Option D
Detailed Explanation
The F–C bond exhibits σ and π characteristics due to the involvement of back-bonding, where the d-orbitals of the metal can interact with the p-orbitals of carbon. This interaction stabilizes the bond and allows for the formation of π-bonds alongside the σ-bond. Other options are not relevant as they do not provide any information or context related to the bonding characteristics of the F–C bond, making them incorrect. Understanding the role of back-bonding is crucial in explaining the hybridization and bond strength in organometallic compounds.
