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.


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.


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?

AlCl3 can precipitate with compounds that contain chloride ions, such as NaCl, KCl, or HCl, to form insoluble AlCl3 complexes. This reaction can be used for the precipitation of aluminum ions from a solution.


What monosaccharides never bond in nature to form a dimer?

Deoxyribose and ribose are monosaccharides that do not bond in nature to form a dimer. They are typically found as single monosaccharide molecules and are not known to form dimers with each other.


What is the chemical formula for Aluminum Chlorine?

How many molecules does alcl3 dissociate into?

1 mole of AlCl3 will dissociate into 4 moles of ions in aqueous solution: 1 mole of Al+3 ions and 3 moles of Cl- ions.


How many small molecules are joined to form a dimer?

A dimer is formed when two small molecules are joined together through chemical bonds. This results in a molecule consisting of two of the same or different subunits.


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.


Is AlCl3 considered a Lewis acid?

Yes, AlCl3 is considered a Lewis acid because it can accept a pair of electrons from a Lewis base to form a coordinate covalent bond.


What is the bond of AlCl3?

Aluminum chloride (AlCl3) is an ionic compound, with aluminum typically forming a +3 cation and chlorine forming a -1 anion to bond together. In the solid state, aluminum chloride exists as a lattice structure of alternating Al3+ and Cl- ions held together by strong ionic bonds.


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.
