O=PCl 3 + 3 H 2 O → O=P(OH) 3 + 3 HCl. Intermediates in the conversion have been isolated, including pyrophosphoryl chloride, O(−P(=O)Cl 2) 2. [9] Upon treatment with excess alcohols and phenols, POCl 3 gives phosphate esters: O=PCl 3 + 3 ROH → O=P(OR) 3 + 3 HCl. Such reactions are often performed in the presence of an HCl acceptor such ...
PCl 3 + 3 H 2 O → H 3 PO 3 + 3 HCl. Phosphorus trichloride is the precursor to organophosphorus compounds. It reacts with phenol to give triphenyl phosphite: 3 PhOH + PCl 3 → P(OPh) 3 + 3 HCl (Ph = C 6 H 5) Alcohols such as ethanol react similarly in the presence of a base such as a tertiary amine: [9] PCl 3 + 3 EtOH + 3 R 3 N → P(OEt) 3 ...
Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.

Skeletal structural formula of Vitamin B 12.Many organic molecules are too complicated to be specified by a molecular formula.. The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are connected to one another. [1]
Structure of boron trifluoride, an example of a molecule with trigonal planar geometry.. In chemistry, trigonal planar is a molecular geometry model with one atom at the center and three atoms at the corners of an equilateral triangle, called peripheral atoms, all in one plane. [1]
This trigonal bipyramidal structure persists in nonpolar solvents, such as CS 2 and CCl 4. [5] In the solid state PCl 5 is an ionic compound called tetrachlorophosphonium hexachlorophosphate formulated PCl + 4 PCl − 6. [6] Structure of solid phosphorus pentachloride, illustrating its autoionization at higher concentrations. [7]
Structure of 2,2'-biphenylene phosphorochloridite.. Phosphorochloridites are produced by partial alcoholysis of phosphorus trichloride, which proceeds stepwise: [1]. PCl 3 + ROH → HCl + (RO)PCl 2 (phosphochloridite)
