noun
conjugation
An arrangement of chemical bonds that allows electrons to spread across several atoms.
In this molecule, conjugation lets electrons spread across several atoms.
Etymology
The Latin root means to yoke together. Chemical conjugation names the linking of neighboring bonding systems so electrons can be shared across more than a single pair of atoms.
More examples
- Alternating single and double bonds often produce conjugation.
- Breaking conjugation changes the wavelengths of light the molecule absorbs.
- Greater conjugation can make a dye absorb visible light.
