The four isomers of C4H9Br are four isomeric alkyl bromides. 1-bromobutane is also known as n-butyl bromide, 2-bromobutane is also known as sec-butyl bromide, 1-bromo-2-methylpropane is also known as isobutyl bromide, and 2-bromo-2-methylpropane is also known as t-butyl bromide.
A chemical isomer is a compound that has the same chemical formula yet has different structural makeups. The theory of chemical isomers was created by Werner and is called Werner's theory.
Butyl bromide (C4H9Br) has a molecular weight of 137.01826 and is considered to be a highly flammable chemical that is prone to fires and explosions if ignited by heat, sparks, or flames. The vapors, if released into the air, can form explosive mixtures. However, it is also found in food and medicine. Butyl bromide is safe when used responsibly in the lab and handled by qualified individuals. If put in the wrong hands, it can be dangerous. It is used in several patents including a United States patent for renin inhibitors. Butyl bromide varies in color and is either colorless or a pale, tan or yellow straw-colored liquid.Learn more about Chemistry
