Sulfur hexafluoride (SF 6) is an inorganic, colorless, odorless, non-flammable, extremely potent greenhouse gas which is an excellent electrical insulator.SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule.Typical for a nonpolar gas, it is poorly soluble in water but soluble in nonpolar organic solvents.It is generally transported as a liquefied compressed gas.F 6 is used as a contrast agent for ultrasound imaging. Sulfur hexafluoride microbubbles are administered in solution through injection into a peripheral vein. These microbubbles enhance the visibility of blood vessels to ultrasound.
The hydrogen fluoride, HF, molecule is polar by virtue of polar covalent bonds â in the covalent bond electrons are displaced toward the more electronegative fluorine atom. Ammonia, NH 3, molecule the three NâH bonds have only a slight polarity (toward the more electronegative nitrogen atom).
