  • Q1
    What is hyperconjugation?
    A stabilizing interaction that occurs when a filled bonding orbital, or antibonding orbital, overlaps with an adjacent empty (or partially-filled) non-bonding orbital or antibonding orbital.
    The attraction between a sigma bond and a pi bond.
    The repulsion between two sigma bonds in the same molecule.
    A process by which electrons occupying a sigma bond convert into an adjacent pi bond.
