Aluminum Bromide Formula

The chemical formula for aluminum bromide is AlBr3.

The formula tells us that each molecule of aluminum bromide contains one aluminum atom and three bromine atoms. The aluminum atom has a 3+ charge, while each bromine atom has a 1- charge. This means that the overall charge of the molecule is neutral, since (+3) + (-1) x 3 = 0.

Aluminum bromide is an ionic compound, which means that it is composed of positively charged metal ions (in this case, aluminum) and negatively charged nonmetal ions (bromine). These ions are held together by strong electrostatic forces of attraction, creating a crystal lattice structure.

Aluminum bromide is commonly used as a Lewis acid catalyst in organic synthesis reactions. It can also be used to prepare other compounds, such as alkyl halides and Grignard reagents.
