What is the hybridization for the middle carbon in acetone? What is the hybridization for the middle C in acetone? What are substituents in organic chemistry? How many bonds can each atom make without hybridization? What is the hybridization of SF6?
Does SF6 have a dipole moment? What is an adduct in organic chemistry? What is metamerism in organic chemistry? Does BF3 have a dipole moment? What is hv in organic chemistry? Decide whether each of the compounds listed is polar or nonpolar. If polar, show the dipole moment. (Hint: You...
The reaction systems e + SF6 SF6 →SF5 + F, H + CH3 CH4, 2 CF2 C2F4, H + O2 →HO2, HO + O HO2 H + O2, and C + HO →CHO are chosen as representative examples. The necessity to know precise thermochemical data is emphasised. The interplay between attractive and anisotropic ...
What causes partial discharge in transformer? Since gas insulated switchgear (GIS) is filled with SF6 gas as insulation, partial discharge can be caused by floating particles, loose or broken components such as a piece of metal shaving that gets too close to a conductor. What lb means? Roman...
There is another “industrial” gas that is often mentionned among the experts, sulfur hexafluoride (SF6). It is used, for example, to fill transformers (that require gases that stay inert in extreme conditions) or…double glazings. It is not emitted in large quantities, but is even more ...
Lewis structures tell us the electron geometry of a molecule. The molecular geometry of a molecule is determined from its Lewis structure and VSEPR (valence shell electron pair repulsion) theory. The number of bonds and lone pair of electrons around the central atom of a molecule tell us its ...

Valency can vary depending on the context and the particular atom in question. For example, sulfur has a valency of 2 in hydrogen sulfide (H2S) but a valency of 6 in sulfur hexafluoride (SF6). Covalency, on the other hand, is generally fixed for a given bond; for example, the covalency...
