Answer:

Explanation:

Bromobenzene:

Aryl halide bromobenzene with the formula C6H5Br. Even though older samples can appear yellow, the liquid is colourless. In organic synthesis, it serves as a reagent.

Bromine reacts with benzene to form bromobenzene in the presence of Lewis acid catalysts like ferric or aluminium chloride. 

A phenyl group is added to other molecules using bromobenzene. One approach entails converting it to phenyl magnesium bromide, a Grignard reagent. When combined with carbon dioxide, this reagent can be used, for example, to create benzoic acid.  Other techniques use Suzuki-like coupling processes that are palladium-catalyzed. A precursor utilized in the production of phencyclidine is bromobenzene.

The simplest member of the class of bromo benzenes is bromobenzene, which is benzene in which one hydrogen has been replaced by a bromine. It is employed as a solvent, particularly for large-scale crystallizations and the insertion of phenyl groups in organic synthesis. It is a liquid at room temperature (m.p. -30°C; b.p.760 156°C). It functions as a mouse metabolite, a hepatotoxic agent, and a non-polar solvent. It is a bromoarene, a volatile chemical compound, and a member of the bromobenzene family.

CH₃CH₂ONa at 25°C
