What Is The Chemical Formula For Aluminium Bromide?

The chemical formula for aluminium bromide is AlBr3. It is a compound composed of one aluminium atom (Al) and three bromine atoms (Br). The subscript "3" after the Br indicates that there are three bromine atoms present in the compound.

Aluminium bromide is an ionic compound, which means that it consists of positively charged ions (Al3+) and negatively charged ions (Br-). In this compound, the aluminium atom loses three electrons to become a positively charged ion (Al3+), while each bromine atom gains one electron to become a negatively charged ion (Br-). The resulting compound has a neutral charge because the total positive charge from the aluminium ions is balanced by the total negative charge from the bromine ions.

Chemically, aluminium bromide is a highly reactive substance that can easily react with water, alcohols, and other compounds containing hydroxyl (-OH) groups. It is commonly used as a catalyst in organic synthesis reactions, such as Friedel-Crafts acylation and alkylation.
