Because the electronegativity difference between aluminum and chlorine is not very high, despite the fact that Al is a metal and Cl is a non-metal. This means the compound will have high covalent character, and will do certain things chemically that molecular compounds do, like form molecules, and bond in an amount that isn't lowest possible terms.

Why does alcl3 exist as al2cl6 molecule n discuss shape of its molecule?
First, draw an AlCl3 molecule, in dot-structure. You will see that in the molecule, Aluminum has only 6 electrons, 3 of which are shared with the chlorine atoms. It needs 2 more electrons to become more stable (8 electrons in the outer shell is usually stable). Now look at the chlorine atom in the AlCl3 molecule.It has 8 electrons, and thus, it is somewhat "stable". If a Chlorine atom from ANOTHER AlCl3 molecule formed a dative bond with the Aluminum atom(a dative bond is a covalent bond where both shared electrons come from just one species. In this case, both electrons come from the chlorine atom), this Al atom would now have 8 electrons as well. That is why AlCl3 exists as a dimer- as Al2Cl6 . It's structure is shown in this picture.
What molecules are non polar?
NO, CO SO2or AlCl3
What is the compound Al2Cl3?
Aluminum chloride, with the chemical formula Al2Cl6, is a white or colorless solid compound that is highly soluble in water. It is commonly used in industrial processes such as in the production of organic compounds and as a catalyst for Friedel-Crafts reactions.
What is meant by anhydrous AlCl3?
Anhydrous AlCl3 refers to aluminum chloride that is free from water molecules. It is a dry, solid compound that is commonly used as a catalyst in chemical reactions. Its anhydrous form is important in certain reactions where the presence of water can interfere with the desired outcome.
What kind of bond in AlCl3 have?
AlCl3 at high temperatres in the vapor phase is molcular, planar AlCl3. with polar covalent bonds. In the melt and at lower temperatures in the vapor phase it is dimeric, Al2Cl6 with two bridging Cl atoms ( Cl2AlCl2AlCl2), each aluminium atom is approximately surrounded by a tetrahedron of Cl atoms. in the solid the structure has each Al surrounded by 6 Cl atoms and the bonding is more ionic in nature. As the solid is heated just before it melts the electrical conductivity rises due to the presence of ions.
Why unhydrated alcl3 is covalent in nature but hydrated alcl3 becomes ionic in nature?
Unhydrated AlCl3 has a covalent nature because it exists as discrete molecules with covalent bonds between aluminum and chlorine atoms. When AlCl3 is hydrated, water molecules bind to the Al3+ cation through ionic interactions, disrupting the covalent bonds within AlCl3 molecules and shifting the overall nature of the compound to ionic.
Why does AlCl3 form a dimer?
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 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
How many Al atoms and how many Cl atoms are in aluminum chloride?
The ratio in aluminum chloride is 1:3 aluminum to chloride ( AlCl3 or Al2Cl6 )
What molecules are non polar?
NO, CO SO2or AlCl3
Which of the following molecules is non-polar CO SO2 NO AlCl3?
AlCl3 is the only non-polar molecule in the list provided. The other molecules (CO, SO2, and NO) have polar covalent bonds due to differences in electronegativity between the atoms involved, making them polar molecules. AlCl3 has a symmetrical arrangement of polar covalent bonds, resulting in a non-polar molecule overall.
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.
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 the compound Al2Cl3?
Aluminum chloride, with the chemical formula Al2Cl6, is a white or colorless solid compound that is highly soluble in water. It is commonly used in industrial processes such as in the production of organic compounds and as a catalyst for Friedel-Crafts reactions.
How many atoms are there in aluminum chloride?
Aluminum chloride has the chemical formula AlCl3. This means one aluminum atom is bonded to three chlorine atoms. Therefore, in one molecule of aluminum chloride, there are a total of 4 atoms (1 aluminum atom + 3 chlorine atoms).
