Valence shell electron pair repulsion
(VSEPR) theory is a model in chemistry used to predict the shape of individual molecules based upon the extent of electron-pair electrostatic repulsion.[1] It is also named Gillespie-Nyholm theory after its two main developers. The acronym "VSEPR" is sometimes
pronounced "vesper" for ease of
pronunciation; however, the phonetic
pronunciation is technically more correct.
Aluminium chloride (AlCl3) is the main compound of aluminium and chlorine. It is white, but samples are often
contaminated with iron trichloride,
giving it a yellow colour. The solid has a
low melting and boiling point. It is
mainly produced and consumed in the
production of aluminium metal, but large amounts are also used in other
areas of chemical industry. The
compound is often cited as a Lewis acid. It is an example of an inorganic
compound that "cracks" at mild
temperature, reversibly changing from
a polymer to a molecule
The correct compound name for AlCl3 is aluminum chloride.
Aluminum chloride (AlCl3) is soluble in water.
The bond angle of AlCl3 is 120 degrees.
The name of the ionic compound AlCl3 is aluminum chloride.
The van't Hoff factor for AlCl3 is 4. AlCl3 dissociates into Al3+ and 3Cl- ions when it dissolves in water, resulting in a total of 4 ions in solution per formula unit of AlCl3.
It depends on the phase and the temperature Solid AlCl3 has each aluminium is 6 coordinate, surrounded by 6 chlorine atoms in an octahedral formation. The best description here is a ionic bonding. Interestingly just below melt temperature the conductivity rises indicating free ions. AlCl3 in the melt is found as dimer Al2Cl6 with four coordinate aluminium. Two chlorines bridging the aluminium atoms. In this aluminium achieves its octet and the bond angles are in line with VSEPR theory. At high temperature the dimers dissociate to monomeric AlCl3 which is trigonal planar, following VSEPR theory.
Yes, AlCl3 is a strong electrolyte.
