Definitions:

Conjugated

Refers to a system in organic chemistry where alternating single and multiple bonds result in enhanced stability and unique reactivity.

Carbocation Intermediate

A positively charged carbon ion, often found as a reactive intermediate in organic reactions, characterized by a carbon atom having only six electrons in its valence shell.

Resonance Contributors

Describes the various Lewis structures that represent a molecule's bonding and electron arrangement, highlighting how electrons can delocalize across the molecule.

Carbocation Intermediate

A positively charged ion (cation) characterized by the presence of a carbon atom having only six electrons in its valence shell, often occurring in organic reactions.
