Five organic compounds have these displayed structures.
Compound A has a four-carbon straight chain with only single bonds, and every carbon is attached to hydrogen atoms.
Compound B has four carbon atoms with a carbon-carbon double bond between the second and third carbons, with hydrogen atoms attached.
Compound C has four carbon atoms with a carbon-carbon double bond between the first and second carbons, with hydrogen atoms attached.
Compound D has two carbon atoms joined by a single bond, and each carbon is bonded to a bromine atom and hydrogen atoms.
Compound E has a chain of three carbon atoms, with bromine atoms attached to the first and last carbon atoms and hydrogen atoms attached.
