Bromobenzene ( C6H5Br ) is an aromatic halogenated hydrocarbon. The molecule is built up, such as benzene, any of the six hydrogen atoms of the benzene is substituted by a bromine atom. It is a colorless, flammable liquid with characteristic odor. It is substantially non-polar, insoluble in water, therefore, in an alcohol, benzene, chloroform, and ethers. Bromobenzene is very volatile; the vapors are much heavier than air and may at the substance is heated above its flash point ( 51 ° C) with the air to form explosive mixtures.

Representation

Bromobenzene can be prepared by electrophilic substitution on the aromatic ring selected from benzene and bromine.

Here, Lewis acids such as aluminum bromide ( AlBr3 ) or tribromide ( FeBr3 ) are used as catalyst in the rule.

Use

Bromobenzene is used as a solvent and as a feedstock for chemical syntheses. It is a popular base for Grignard compounds.

Safety

• Inhalation or ingestion can lead to health
• May cause respiratory, digestive tract, eyes and skin irritation and damage, to the shortness of breath and loss of consciousness
