| 11. | Studies show that tautomer II is most common in ethanol, water, and DMSO.
|
| 12. | The position of the nitrogen with the hydrogen on it determines how the tautomer is named.
|
| 13. | Sometimes the minor tautomer is called hypophosphorous acid and the major tautomer is called phosphinic acid.
|
| 14. | Sometimes the minor tautomer is called hypophosphorous acid and the major tautomer is called phosphinic acid.
|
| 15. | It is a tautomer of ethynol.
|
| 16. | HOP ( O ) H 2 exists in equilibrium with the minor tautomer HP ( OH ) 2.
|
| 17. | Through movement of this hydrogen and electrons, the second tautomer form, 2-hydroxypyridine is formed.
|
| 18. | Glutaconic anhydride, which forms by dehydration the diacid, exists mainly as the dicarbonyl tautomer in solution.
|
| 19. | Thebacon is generated by the esterification product of the enol tautomer of hydrocodone ( dihydrocodeineone ) with acetic acid.
|
| 20. | The tautomer on the left, featuring a 4-hydroxy group, the C4 carbon, is dominant.
