As a chemistry expert with extensive knowledge in the field, I'm delighted to delve into the nature of the compound aluminum chloride, or AlCl3. To address the question of whether AlCl3 is ionic or covalent, it's essential to understand the fundamental differences between these two types of chemical bonds.
Ionic bonds are formed when electrons are transferred from one atom to another, resulting in the formation of positively and negatively charged ions that are attracted to each other. This type of bonding is typically found in compounds composed of a metal and a nonmetal, where the metal loses electrons and the nonmetal gains them.
Covalent bonds, on the other hand, occur when two atoms share electrons. This is common in compounds made up of nonmetals, where atoms share electrons to achieve a stable electron configuration.
Now, let's consider the specific case of AlCl3. Aluminum is a metal, and chlorine is a nonmetal. According to traditional rules, one might predict that AlCl3 would form an ionic bond, as metals tend to lose electrons and nonmetals tend to gain them. However, the nature of the bond in AlCl3 is not as straightforward as it might seem.
Aluminum in AlCl3 has a +3 charge, and each chlorine atom has a -1 charge. The high charge on the aluminum ion (Al3+) is significant. It has the ability to polarize the electron cloud of the chlorine atoms, which is a phenomenon where the electron density is distorted towards the positively charged ion. This polarization can lead to a sharing of electrons between the aluminum and chlorine atoms, which is characteristic of covalent bonding.
However, it's important to note that while there is electron sharing, the bond is not purely covalent. The bond in AlCl3 is described as a polar covalent bond. This means that there is a significant difference in electronegativity between aluminum and chlorine, leading to an unequal sharing of electrons. The chlorine atoms are more electronegative and thus attract the shared electrons more strongly, creating a bond with a distinct polarity.
To summarize, AlCl3 is not an ionic compound as one might initially predict based on the presence of a metal and nonmetal. Instead, it forms a polar covalent bond due to the high charge on the aluminum ion and the polarization of the chlorine electron cloud. This results in an unequal sharing of electrons, with the chlorine atoms exerting a stronger pull on the shared electrons.

Al3+ is highly charged in nature and it can polarise the electron clouds of Cl to a large extent. So, electrons get shared between the two ions. Hence the compound is a covalent one, but the bond is polar covalent. ... AlCl3 Although a metal- nonmetal compound, AlCl3 is not ionic (as might be predicted).
