2-Bromobutane is an isomer of 1-bromobutane

1-Bromobutane

1-Bromobutane is a colorless liquid that is insoluble in water, but soluble in ethanol and diethyl ether. As a primary alkyl halide, it is especially prone to SN2 type reactions...

. Both compounds share the molecular formula C₄H₉Br. 2-Bromobutane is also known as sec-butyl bromide or methylethylbromomethane. Because it contains bromine

Bromine

Bromine ") is a chemical element with the symbol Br, an atomic number of 35, and an atomic mass of 79.904. It is in the halogen element group. The element was isolated independently by two chemists, Carl Jacob Löwig and Antoine Jerome Balard, in 1825–1826...

, a halogen, it is part of a larger class of compounds known as alkyl halides. It is a colorless liquid with a pleasant odor. Because the carbon atom connected to the bromine is connected to two other carbons the molecule is referred to as a secondary alkyl halide.

Reactivity

2-Bromobutane is relatively stable, and is flammable. It is prone to undergo an E2 reaction if treated with a strong base, which is a bimolecular elimination which results in an alkene (double bond) product.

Toxicity

2-Bromobutane is an irritant, and harmful if ingested. It can irritate and burn skin and eyes.
