Phosphorus pentafluoride. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Infobox references. Phosphoryl fluoride (commonly called phosphorus oxyfluoride) is a compound with the chemical formula POF3. It is a colorless gas that hydrolyzes rapidly.
Phosphorus pentafluoride, PF5, is a phosphorus halide. It is a colourless, toxic gas that fumes in air.
: a fluoride containing six atoms of fluorine in the molecule.
Phosphorus reacts with all halogens to form phosphorus trihalides. Specifically, it reacts with fluorine: F2, chlorine: Cl2, bromine: Br2, and iodine: I2, to form respectively phosphorus(III) fluoride: PF3, phosphorus(III) chloride: PCl3, phosphorus(III) bromide: PBr3, and phosphorus(III) iodide: PI3.
Phosphorus can have expanded octet, because it can shift it’s lone pair electrons (3s orbital electrons) to empty 3d obital during excited state and thus can form 5 bonds.
Answer: PH5 is formed by the overlap of d orbitals with Sp3d hybridisation. F is more electronegative so Sp3d hybridisation is possible but H has lesser electronegativity and can not form sp3d hybridization and PH5 cannot be formed.
Sodium iodide (chemical formula NaI) is an ionic compound formed from the chemical reaction of sodium metal and iodine.
Nitrogen tetroxide is used as an oxidizing agent in one of the most important rocket propellants because it can be stored as a liquid at room temperature.
N2O4 has an irritating, unpleasant acid-like odor. N2O4 is a very reactive, toxic oxidizer. It is non-flammable with air; however, it will inflame combustible materials.
It is primarily produced in the manufacture of semiconductors and LCD (Liquid Crystal Display) panels, and certain types of solar panels and chemical lasers.
SF6 has high affinity for electrons. When a free electron comes and collides with a neutral gas molecule, the electron is absorbed by the neutral gas molecule and negative ion is formed. This is called as electro negativity of SF6 gas.
Function. The main function of phosphorus is in the formation of bones and teeth. It plays an important role in how the body uses carbohydrates and fats. It is also needed for the body to make protein for the growth, maintenance, and repair of cells and tissues.
White phosphorus is extremely flammable. Phosphorus will spontaneously ignite if exposed to air. Phosphorus ignites at approximately 86°F (30°C) in air; the ignition temperature is higher when the air is dry.

Methane, CH4, is a covalent compound with exactly 5 atoms that are linked by covalent bonds. We draw this covalent bonding as a Lewis structure (see diagram). The lines, or sticks, as we say, represent the covalent bonds. There are four bonds from a central carbon (C) linking or bonding it to four hydrogen atoms (H).
The compound phosphorus pentafluoride is a trigonal bipyramidal structure. It has sp3d hybridization. It has total of 40 valence electrons. The formal charge on phosphorus in this compound is zero.
Molecular compounds are electrically neutral. Ionic compounds are (usually) formed when a metal reacts with a nonmetal (or a polyatomic ion). Covalent compounds are formed when two nonmetals react with each other. Since hydrogen is a nonmetal, binary compounds containing hydrogen are also usually covalent compounds.
Expert Answers Phosphorus and fluorine can combine to form two different compounds. One is phosphorus trifluoride (PF3) and the other is phosphorus pentafluoride (PF5).
Phosphorus and fluorine are both non metals. Therefore the only type of bond they have is covalent (sharing electrons).
PF3 P F 3 is a covalent compound as it is formed by the sharing of electrons between phosphorus and fluorine atoms. Each fluorine atom share one electron with phosphorus and the octet of each atom gets completely filled.
It reacts with many metals and metalloids to form phosphides. Phosphorus atoms can bond with oxygen atoms to form ester groups. These can bond with carbon atoms, yielding a large number of organic phosphorus chemicals. These are found in many important biological processes.
Valency of 3 is due to requirement of 3 more electrons to complete it’s octet. The valency of 5 is due to exitation of an electron from 3s orbitals to 3d orbital . This leads in formation of 5 sp3d hybrid orbitals and hence phosphorous shows a valency of 5.
Sulfur has one more electron pair in its 3s subshell so it can undergo excitation one more time and place the electron in another empty 3d orbital. Now sulfur has 6 unpaired electrons which means it can form 6 covalent bonds to give a total of 12 electrons around its valence shell.
It’s impossible for NH5 to exist. Nitrogen is an n=2 atom, meaning its outer (valence) level is n=2 that level has only 4 orbitals in it so it can form only 4 bonds, one each to a single atom.
PH5 doesn’t exist because d- orbital of P interacts with s-orbital of H. The bond formed via this hybridisation is not stable and energetically unfavourable. Whereas in case of PCL5 both energy and hybridisation of orbitals are stable.
NCl5 does not exist because there are no d-orbitals in the second energy level. Therefore there is no way to arrange five pairs of bonding electrons around a nitrogen atom.
An ionic bond would form, as Na becomes Na+ and Cl becomes Cl-. They are now stuck together as ions in a compound NaCl. But now consider NaI, which definitely does have ionic bonds. Iodine has an electronegativity of 2.5 compared to Na at 0.9, for a difference of 1.6.

IF4 (iodine tetrafluoride) has an octahedral electron geometry, but the molecular geometry states that the atoms take a square planar shape. This is because iodine carries two lone pairs, one above and below the plane on the x-axis.
SbF5 is a strong Lewis acid, exceptionally so toward sources of F− to give the very stable anion [SbF6]−, called hexafluoroantimonate.
