Pi bonds and resonance

Under the framework of valence bond theory, resonance is an extension of the idea that the bonding in a chemical species can be described by a Lewis structure. For many chemical species, a single Lewis structure, consisting of atoms obeying the octet rule, possibly bearing formal charges, and connected by bonds of positive integer order, is sufficient for describing the chemical bondin… WebbThis video lecture is helpful in understanding Pi Bonding in Octahedral Complexes, draw ligand group orbitals and formation of molecular orbitals in Octahedr...

Webb(1) Unsaturated metal sites characteristic of some adsorbents─including those in MOFs and zeolites─are electronically Lewis acidic in nature with minimal π-backbonding capabilities.

WebbCation-Π interactions are important in protein structure. The guanidinium group of arginine and the ε-NH 3 + of lysine engage in cation-Π interactions with aromatic protein sidechains.

WebbRemember that resonance forms occur when various arrangements of π bonds are possible. Since the arrangement of π bonds involves only the unhybridized orbitals, resonance does not influence the assignment of hybridization. For example, molecule benzene has two resonance forms ( [link] ).
