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.
Nonpolar bonds generally occur when the difference in electronegativity between the two atoms is less than 0.5; Polar bonds generally occur when the difference in electronegativity between the two atoms is roughly between 0.5 and 2.0; Ionic bonds generally occur when the difference in electronegativity between the two atoms is greater than 2.0
Selenium tetrachloride is the inorganic compound composed with the formula SeCl 4. This compound exists as yellow to white volatile solid. This compound exists as yellow to white volatile solid. It is one of two commonly available selenium chlorides , the other example being selenium monochloride , Se 2 Cl 2 .
A tetrafluoride is a chemical compound with four fluorines in its formula. List of tetrafluorides ... Selenium tetrafluoride, SeF 4, a liquid at standard conditions;
Dissolution of SeO 2 in selenium oxydichloride give the trimer [Se(O)O] 3. [6] Monomeric SeO 2 is a polar molecule, with the dipole moment of 2.62 D [7] pointed from the midpoint of the two oxygen atoms to the selenium atom. The solid sublimes readily. At very low concentrations the vapour has a revolting odour, resembling decayed horseradishes.
The 3-center 4-electron (3c–4e) bond is a model used to explain bonding in certain hypervalent molecules such as tetratomic and hexatomic interhalogen compounds, sulfur tetrafluoride, the xenon fluorides, and the bifluoride ion.
Most commonly, four bonds to a central atom result in tetrahedral or, less commonly, square planar geometry. 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 ).
Seleninyl fluoride can be produced by the reaction of selenium oxychloride and potassium fluoride. [3] 2 KF + SeOCl 2 → 2 KCl + SeOF 2. It can also be produced by the reaction of selenium tetrafluoride with water or selenium dioxide. [2] SeF 4 + H 2 O → SeOF 2 + 2 HF SeF 4 + SeO 2 → 2 SeOF 2
