AlCl3 is borderline for being ionic/covalent. When solid it is usually ionic. In vapor it is covalent. In this state 3 electrons from Al are shared with 3 Cl electrons. That makes only 6 electrons. To get to the very favorable 8 electron octet, it forms Al2Cl6 and thus the extra sharing from the dimer gives the necessary octet for all atoms.

Is AlCl3 a covalent or ionic compound?
Solid AlCl3 is ionic. Liquid and gaseous AlCl3 is present as a covalent dimer, Al2Cl6. At high temperatures the dimer dissociates to form the planar covalent monomer AlCl3.
What is the bond of AlCl3?
In the solid- ionic with 6 coordinate indiumIn the melt it is a dimer, Al2Cl6, with covalent bondsIn the gas phase at high temperatures a Trigonal Pyramidal monomer AlCl3
How many small molecules are joined to form a dimer?
Two monomers are joined to make a dimer.
Does AlCl3 have covalent bonds?
Yes, pure aluminium chloride has covalent bonds. It actually exists as a dimer Al2Cl6. However, it forms hydrated ions when it dissolves in water.
How many molecules does alcl3 dissociate into?
It does NOT form molecules. When AlCl3 'breakdown ' it form the IONS Al^(3+) & 3 Cl^(-) AlCl3(s) IS a molecule.

What is the dimer of RNA?
The opposite sequence, so the two strands can bind together to form a dimer.

What does alcl3 precipitate with?
Aluminum chloride (AlCl3) can be brought out of solution, that is precipitated into crystalline form. This process requires hydrochloric acid (HCl).
What is the chemical formula for Aluminum Chlorine?
(inorganic chemistry) AlCl3 or Al2Cl6 A deliquescent compound in the form of white to colorless hexagonal crystals; fumes in air and reacts explosively with water; used as a catalyst
Anhydrous alumnium cloride cannot be obtained by heating crystals of AlCl3.6H2O why?
AlCl3 is covalent and hence when the water of crystallisation is evaporated, the AlCl3 will react with the water to form the hydroxide
Is AlCl3 a trigonal planar?
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.
Aluminium burns in chlorine to form aluminium chloride?
yes to produce aluminium chloride AlCl3 vapour which is Al2Cl6 . Aluminium(III) in crystalline AlCl3 are six coordinate, on melting or sublimation (at 150C) the molecule assume the molecular form Al2Cl6
What is meant by anhydrous AlCl3?
anhydrous means without water and anhydrous AlCl3 means, AlCl3 is hydrated in water therefore anhydrous AlCl3 is used.
