• The concept of delocalized chemical bonding via Resonance.

• Resonance in 1,3-butadiene molecule.

• The concept of more contributing canonical form explained via examples – rules of resonance.

• Resonance in diazomethane.

• Attention has been given to a simple understanding of how to draw resonance structures.

• Explaining Hyperconjugation – The concept of “No bond resonance”.

• Which molecules can exhibit Hyperconjugation? The important condition explained.

• Tips and tricks to write correct Hyperconjugation structures – explained with a series of examples.

• The outcome of Hyperconjugation – How it affects various carbon-containing species and groups.

• Practice problems emphasizing the application of Hybridization, Resonance and Hyperconjugation in predicting and explaining molecular properties in organic compounds.

In short, this course explains the idea of Hybridisation and its correlation with geometry, bonding and other properties in carbon-containing compounds. The concept of delocalized chemical bonding via Resonance with an emphasis on the stability of various resonating structures has been discussed. The clarity on the concept of "No Bond Resonance" for Hyperconjugation has been provided.
