aromaticity

9.7
A property of ring-shaped molecules that makes them unusually stable because their electrons spread around the ring
  • noun

  • The phenomenon of aromaticity allows compounds like toluene to be less reactive than expected due to their stable electron configuration.

Examples

  • As pyrolysis temperature increased, the aromaticity, crystallinity, and ash content increased.

  • Biochar characteristics resulting in potential carbon sequestration (carbon aromaticity and crystallinity) and improving soil fertility and crop yield (increased ash content and CEC) were identified.

  • The stability of benzene is largely due to its aromaticity, which results from the delocalization of electrons in the ring.

  • Understanding aromaticity is crucial for predicting the behavior of many organic compounds in chemical reactions.

aromaticity singular
aromaticities plural

Morphology

aromaticity = aromatic (opaque) = aroma + tic + ity

The step from the adjective 'aromatic' to the noun 'aromaticity' is a regular nominalization (adding -ity).

Etymology

Aromaticity in chemistry gets its name from aroma ('smell') because early chemists noticed many ring compounds had strong scents. A helpful way to remember is that the word links to smell, but in science aromaticity now means a special stability of ring-shaped molecules because their electrons are shared around the ring.
