Question

what is hyper configuration​

Answer 1

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.

hope it helps☺

Answer 2

In organic chemistry, hyperconjugation is the interaction of the electrons in a sigma orbital with an adjacent empty non-bonding or antibonding σ or π orbital to give an extended molecular orbital. Increased electron delocalization associated with hyperconjugation increases the stability of the system.
