Is POCl3 a polar molecule?
The molecular geometry of POCl3 is tetrahedral with asymmetric charge distribution around the central atom. Therefore this molecule is polar.
Why is P central atom in POCl3?
Step 1: Connect the atoms with single bonds. The less electronegative is the phosphorous atom. Hence, the P atom is going to be the central atom. Recall that electronegativity decreases as we move away from the fluorine atom in the periodic chart.Jul 8, 2013

What is a point group in chemistry?
A Point Group describes all the symmetry operations that can be performed on a molecule that result in a conformation indistinguishable from the original. Point groups are used in Group Theory, the mathematical analysis of groups, to determine properties such as a molecule's molecular orbitals.Oct 14, 2020
What is point group and space group?
Point groups and space groups are terms described under crystallography. The crystallographic point group is a set of symmetry operations all of which leave at least one point unmoved. A space group is the 3D symmetry group of a configuration in space.Mar 15, 2018
What is a point group in physics?
point group, also called Crystal Class, in crystallography, listing of the ways in which the orientation of a crystal can be changed without seeming to change the positions of its atoms.
What is the formula for phosphoryl chloride?
Phosphoryl chloride (commonly called phosphorus oxychloride) is a colourless liquid with the formula P O Cl 3. It hydrolyses in moist air releasing phosphoric acid and fumes of hydrogen chloride. It is manufactured industrially on a large scale from phosphorus trichloride and oxygen or phosphorus pentoxide. It is mainly used to make phosphate esters such as tricresyl phosphate .
What is POCl 3?
POCl 3 can also act as a Lewis base, forming adducts with a variety of Lewis acids such as titanium tetrachloride : The aluminium chloride adduct (POCl 3 ·AlCl 3) is quite stable, and so POCl 3 can be used to remove AlCl 3 from reaction mixtures, for example at the end of a Friedel-Crafts reaction .
What is phosphoryl chloride used for?
In one commercial application, phosphoryl chloride is used in the manufacture of phosphate esters. Triarylphosphates such as triphenyl phosphate and tricresyl phosphate are used as flame retardants and plasticisers for PVC. Trialkylphosphates such as tributyl phosphate are used as liquid–liquid extraction solvents in nuclear reprocessing ...
What is the boiling point of POCl 3?
With a freezing point of 1 °C and boiling point of 106 °C, the liquid range of POCl 3 is rather similar to water. Also like water, POCl 3 autoionizes, owing to the reversible formation of POCl 2+ ,Cl − .
What is tributyl phosphate used for?
Trialkylphosphates such as tributyl phosphate are used as liquid–liquid extraction solvents in nuclear reprocessing and elsewhere. In the semiconductor industry, POCl 3 is used as a safe liquid phosphorus source in diffusion processes. The phosphorus acts as a dopant used to create n-type layers on a silicon wafer.
What is the reaction of POCl 3?

What is a point group?
In geometry, a point group is a group of geometric symmetries ( isometries) that keep at least one point fixed. Point groups can exist in a Euclidean space with any dimension, and every point group in dimension d is a subgroup of the orthogonal group O ( d ). Point groups can be realized as sets of orthogonal matrices M ...
Do point groups have infinite families?
Discrete point groups in more than one dimension come in infinite families, but from the crystallographic restriction theorem and one of Bieberbach's theorems, each number of dimensions has only a finite number of point groups that are symmetric over some lattice or grid with that number.
What is the Coxeter notation?
Coxeter notation offers a bracketed notation equivalent to the Coxeter diagram, with markup symbols for rotational and other subsymmetry point groups. Reflection groups are necessarily achiral (except for the trivial group containing only the identity element).
Overview
Physical properties
With a freezing point of 1 °C and boiling point of 106 °C, the liquid range of POCl3 is rather similar to water. Also like water, POCl3 autoionizes, owing to the reversible formation of POCl2 ,Cl .
Structure
Like phosphate, phosphoryl chloride is tetrahedral in shape. It features three P−Cl bonds and one strong P=O double bond, with an estimated bond dissociation energy of 533.5 kJ/mol. On the basis of bond length and electronegativity, the Schomaker-Stevenson rule suggests that the double bond form is dominant, in contrast with the case of POF3. The P=O bond involves th…
Chemical properties
POCl3 reacts with water to give hydrogen chloride and phosphoric acid:
O=PCl3 + 3 H2O → O=P(OH)3 + 3 HCl
Intermediates in the conversion have been isolated, including pyrophosphoryl chloride, P2O3Cl4.
Upon treatment with excess alcohols and phenols, POCl3 gives phosphate esters:
O=PCl3 + 3 ROH → O=P(OR)3 + 3 HCl
Preparation
Phosphoryl chloride can be prepared by many methods. Phosphoryl chloride was first reported in 1847 by the French chemist Adolphe Wurtz by reacting phosphorus pentachloride with water.
The commercial method involves oxidation of phosphorus trichloride with oxygen:
2 PCl3 + O2 → 2 POCl3
An alternative method involves the oxidation of phosphorus trichloride with potassium chlorate:
Uses
In one commercial application, phosphoryl chloride is used in the manufacture of phosphate esters. Triarylphosphates such as triphenyl phosphate and tricresyl phosphate are used as flame retardants and plasticisers for PVC. Trialkylphosphates such as tributyl phosphate are used as liquid–liquid extraction solvents in nuclear reprocessing and elsewhere.
