3Bromohexane

3-Bromohexane is an organobromine compound with the chemical formula C6H13Br. It is a halogenated alkane, specifically a secondary alkyl halide, where a bromine atom is attached to the third carbon atom of a six-carbon chain. At room temperature and pressure, 3-bromohexane typically exists as a colorless liquid. Its molecular weight is approximately 165.07 grams per mole. It is sparingly soluble in water but generally miscible with common organic solvents such as ethanol, diethyl ether, and acetone.

The synthesis of 3-bromohexane can be achieved through various chemical reactions. A common method involves the free-radical bromination of hexane, although this often leads to a mixture of isomers. A more regioselective approach can involve the hydrobromination of 2-hexene or the reaction of 3-hexanol with a brominating agent like phosphorus tribromide (PBr3) or concentrated hydrobromic acid (HBr).

In terms of chemical properties, 3-bromohexane undergoes typical reactions of secondary alkyl halides. It can participate in nucleophilic substitution reactions (SN1 and SN2 mechanisms) and elimination reactions (E1 and E2 mechanisms), depending on the reaction conditions and the nature of the nucleophile or base used. These reactions can lead to the formation of various hexyl derivatives, including alcohols, ethers, amines, and alkenes. 3-Bromohexane is considered a moderately reactive compound.
