The seesaw geometry occurs when a molecule has a steric number of 5, with the central atom being bonded to 4 other atoms and 1 lone pair (AX 4 E 1 in AXE notation). An atom bonded to 5 other atoms (and no lone pairs) forms a trigonal bipyramid with two axial and three equatorial positions, but in the seesaw geometry one of the atoms is replaced ...
A molecule may be polar either as a result of polar bonds due to differences in electronegativity as described above, or as a result of an asymmetric arrangement of nonpolar covalent bonds and non-bonding pairs of electrons known as a full molecular orbital. While the molecules can be described as "polar covalent", "nonpolar covalent", or ...
The name octasulfur is the most commonly used for this chemical. It is systematically named cyclo-octasulfur (which is the preferred IUPAC name) and cyclooctasulfane.It is also the final member of the thiocane heterocylic series, where every carbon atom is substituted with a sulfur atom, thus this sulfur allotrope is systematically named octathiocane as well.
Lipophilicity (from Greek λίπος "fat" and φίλος "friendly") is the ability of a chemical compound to dissolve in fats, oils, lipids, and non-polar solvents such as hexane or toluene. Such compounds are called lipophilic (translated as "fat-loving" or "fat-liking" [1] [2]). Such non-polar solvents are themselves lipophilic, and the ...
Tellurium tetrachloride is the inorganic compound with the empirical formula TeCl 4. The compound is volatile, subliming at 200 °C at 0.1 mmHg. [2] Molten TeCl 4 is ionic, dissociating into TeCl 3 + and Te 2 Cl 10 2−. [2]
Selenium tetrafluoride (Se F 4) is an inorganic compound.It is a colourless liquid that reacts readily with water. It can be used as a fluorinating reagent in organic syntheses (fluorination of alcohols, carboxylic acids or carbonyl compounds) and has advantages over sulfur tetrafluoride in that milder conditions can be employed and it is a liquid rather than a gas.
Silicon disulfide is the inorganic compound with the formula Si S 2. Like silicon dioxide , this material is polymeric , but it adopts a 1-dimensional structure quite different from the usual forms of SiO 2 .
Silicon tetrafluoride or tetrafluorosilane is a chemical compound with the formula Si F 4.This colorless gas is notable for having a narrow liquid range: its boiling point is only 4 °C above its melting point.
