2-Bromobutane

Because it contains bromine, 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.

When treated with a strong base, it is prone to undergo an E2 reaction, which is a bimolecular elimination reaction, resulting in (predominantly) 2-butene, an alkene (double bond).

It can irritate and burn skin and eyes.
