SF6 has an octahedral geometry: (Image from ChemEd DL. ) When I first encountered SF6 and the term octahedral, I was puzzled by it as SF6 only has six bonds. Why the "oct-" (eight) prefix? Well, it turns out that if you draw a line between each of the adjacent fluorine atoms, you get an octahedronIn ethyne molecule, each carbon atom is Sp-hybridized. Due to Sp-hybridization each carbon atom generates two Sp-hybrid orbitals. In this way there exists four Sp-orbital in ethyne. These Sp-orbital are arranged in linear geometry and 180 o apart. Remaining py and pz unhybrid orbitals of each carbon atom lie perpendicular to the plane of Sp ...

As SF6 is colorless, odorless, and not flammable, it is nearly impossible to detect with the naked eye. A commonly used tool to detect this invisible gas is the so-called ‘sniffer,’ a device which measures the concentration of a certain gas in one single location and generates a concentration reading in parts per million (ppm). sf objects can have more than one geometry list-column, but always only one geometry column is considered active, and returned by st_geometry.
