| 1. | The diradical occurs in the two degenerate ? * antibonding orbitals.
|
| 2. | Discrete molecules with a diradical nature are singlet oxygen and triplet oxygen.
|
| 3. | This is because, as a diradical, it has unpaired electrons.
|
| 4. | That is unless the potential energy surface is perturbed to favor the diradical.
|
| 5. | The diradical ground-state normally undergoes abstraction reactions.
|
| 6. | That's 8 orbitals, a double bond, and a diradical.
|
| 7. | Although the Cope rearrangement is diradical.
|
| 8. | These compounds generate the diradical intermediate described above which can cause single and double stranded DNA cuts.
|
| 9. | However, depending on the nature of the dipole and dipolarophile, diradical or zwitterionic intermediates are possible.
|
| 10. | These reaction mechanisms proceed through the lowest free energy transition states compared to the diradical and dyotropic mechanisms.
