Benzyl bromide, or α-bromotoluene, is an organic compound consisting of a benzene ring substituted with a bromomethyl group. The melting point of a solid is the temperature range at which it changes state from solid to Liquid. The boiling point of a liquid is the temperature at which the Vapor pressure of the liquid equals the environmental pressure surrounding the liquid In Chemistry, the standard state of a material is its state at 1 bar (100 Kilopascals exactly An organic compound is any member of a large class of Chemical compounds whose Molecules contain Carbon. Benzene, or benzol, is an organic Chemical compound and a known Carcinogen with the molecular formula C 6 H 6 It can be prepared by the bromination of toluene at room temperature in air, using manganese(IV) oxide as a heterogeneous catalyst. Toluene, also known as methylbenzene or phenylmethane, is a clear water -insoluble liquid with the typical smell of Paint thinners redolent of Manganese(IV oxide is the Chemical compound MnO2 commonly called manganese dioxide. It is a colorless liquid that is decomposed slowly in water.
Benzyl bromide is used in organic synthesis for the introduction of the benzyl protecting group for alcohols and carboxylic acids. Organic synthesis is a special branch of Chemical synthesis and is concerned with the construction of Organic compounds via Organic reactions Organic A protecting group or protective group is introduced into a molecule by chemical modification of a Functional group in order to obtain Chemoselectivity In Chemistry, an alcohol is any Organic compound in which a Hydroxyl group ( - O[[hydrogen H]]) is bound to a Carbon Carboxylic acids are Organic acids characterized by the presence of a Carboxyl group, which has the formula -C(=OOH usually written -COOH or -CO2H
Benzyl bromide is a strong lachrymator and is also intensely irritating to skin and mucous membranes. A lachrymatory agent or lachrymator (from lacrima meaning "a tear " in Latin) (commonly referred to as tear gas) is a Because of these properties, it has been used as a war gas.
Synthesis
Benzyl bromide can be synthesized by the bromination of toluene:
