Which of the following show hyperconjugation
Hi Candidate,
First let's know about the basis of Hyper Conjugation- Hyperconjugation is the stabilising interaction that results from the interaction of the electrons in a σ-bond (usually C-H or C-C) with an adjacent empty or partially filled p-orbital or a π-orbital to give an extended molecular orbital that increases the stability of the system.
Hyper conjugation may not be the most dominant effect such as Resonance but the role of Hyper conjugation is necessary for charge stabilisation.
All The Best.
