Why is BCl3 a monomer whereas AlCl3 exists as a dimer? STABILITY , As it is seen in the following figure The bond length and atomic size of boron in BCl3 are smaller than in AlCl3 so this leads to interatomic repulsion so BCl3 could not accept another BCl3 via a dative bond because it leads to more repulsion and finally breaking of dimer.

Important CHEM 2060 Course Goal = Finding The Point Group ! ***You must become adept at assigning point groups to molecules in this part of the course. You can use a truth/decision table if you wish. Ultimately, you should strive to learn, understand and be able to apply the method below

The point group assignment depends on how the pairs of spokes (attached to both the front and back of the hub) connect with the rim. If the pairs alternate with respect to their side of attachment, the point group is D8d. Other arrangements are possible, and different ways in which the spokes cross can affect the point group assignment;

A complete set of symmetry operations that can be performed on a molecule is called the Symmetry Group for that molecule, and satisfies key criteria for a mathematical group. This means that we can use the theorems of group theory (a branch of mathematics) to assist in problems of molecular symmetry. There are four key properties that a set of symmetry operations will obey if they belong to a ... d2h - Point Group Symmetry Character Tables

Ultimately, you should strive to learn, understand and be able to apply the method below Aluminium chloride belongs to the point group D 3h in its monomeric form and D 2h in its dimeric form. Both forms of aluminium chloride, however, do not possess a dipole moment because the bond dipole moments cancel each other out. Safety. Anhydrous AlCl 3 reacts vigorously with bases, so suitable precautions are required. It can cause irritation to the eyes, skin, and the respiratory system if inhaled or on contact.

Symmetry of Molecules and Point Groups . What does symmetry mean? Symmetry (Greek = harmony, regularity) means the repetition of a motif and thus the agreement of parts of an ensemble (Fig. 1). This page looks at the structures of the chlorides of the Period 3 elements (sodium to sulphur), their physical properties and their reactions with water. Chlorine and argon are omitted - chlorine because it is meaningless to talk about "chlorine chloride", and argon because it doesn't form a ...

BCl3 and AlCl3 both are the example of electron deficient compounds, as there are only six electrons in the valency shell of central atom after the formation of the molecule, thus, both the compounds have strong tendency to gain (two) electrons, s...

Structure, properties, spectra, suppliers and links for: Aluminium chloride. The rest are liquids or low melting point solids. Leaving aside the aluminum chloride and phosphorus(V) chloride cases where the situation is quite complicated, the attractions in the others will be much weaker intermolecular forces such as van der Waals dispersion forces.
