CFO- + = CHFO
| Quantity | Value | Units | Method | Reference | Comment |
|---|---|---|---|---|---|
| ΔrH° | 1475. ± 19. | kJ/mol | EIAE | Karpas and Klein, 1977 | gas phase; From HCOF. G3MP2B3 calculations indicate an EA of ca. 2.3 eV, HOF(A-) 7 kcal/mol less stable. |
| ΔrH° | 1463. ± 14. | kJ/mol | Acid | Thynne and MacNeil, 1970 | gas phase; From CF2O |
+ CHFO = (
• CHFO)
By formula: F- + CHFO = (F- • CHFO)
| Quantity | Value | Units | Method | Reference | Comment |
|---|---|---|---|---|---|
| ΔrH° | >75.73 | kJ/mol | IMRB | Karpas and Klein, 1977 | gas phase; FCO- + HCFO ->. Computations indicate HOF(A-) ca. -134, dHaff ca. 33 kcal/mol |
