| 41. | They are generally very strong because of the high electronegativity of fluorine.
|
| 42. | The fluorine-carbon bond is largely ionic producing a strong dipole.
|
| 43. | Fluorine compounds typically have a fast NMR hydrogen-1 NMR spectra.
|
| 44. | Fluorine-containing agrichemicals are measurable in farmland runoff and nearby rivers.
|
| 45. | Several compounds made from elemental fluorine serve the electronics industry.
|
| 46. | These include iodine, fluorine, cyanide, thiocyanate, and isocyanate.
|
| 47. | Pentafluorosulfanylamine reacts with fluorine gas to yield difluoroamino sulfur pentafluoride:
|
| 48. | Water burns in fluorine, suggesting it must contain some chemical energy.
|
| 49. | Most chemists had believed that chemical separation of elemental fluorine was probably impossible.
|
| 50. | Addition of fluorine lowers the dielectric constant of glass.
