| 31. | Natural phenols Stacking, a chemical property of molecules with aromaticity, is seen occurring between phenolic molecules.
|
| 32. | The quantum mechanical origins of this stability, or aromaticity, were first modelled by H�ckel in 1931.
|
| 33. | Although PAHs clearly are aromatic compounds, the degree of aromaticity can be different for each ring segment.
|
| 34. | Thiazoles are characterized by larger pi-electron delocalization than the corresponding oxazoles and have therefore greater aromaticity.
|
| 35. | Biosynthesis of aromaticity is restored via the loss of a proton at the C ( 2 ) atom.
|
| 36. | Independently of Jun-ichi Aihara, he introduced topological resonance energy as a reliable theory of aromaticity.
|
| 37. | Metal aromaticity in metal clusters is another example of delocalization, this time often in three-dimensional entities.
|
| 38. | Y-aromaticity is a concept developed to explain the extraordinary stability and high basicity of the guanidinium cation.
|
| 39. | For residual fuel oil two other empirical indexes are used CII and Calculated Carbon Aromaticity Index ( CCAI ).
|
| 40. | In organic chemistry, the term "'aromaticity "'is used to describe a reactivity ).
