Which of the following compounds react most readily with Br(g)

Explanation

The correct answer is C3H6, which is propene. Alkenes, such as propene, have a carbon-carbon double bond that is more reactive than single or triple bonds found in alkanes and alkynes, respectively. This makes them more susceptible to addition reactions with halogens like bromine. Among the given options, propene is the most reactive with Br(g) due to its unsymmetrical nature, which can lead to more favorable reaction pathways.C2H2 (ethyne) is an alkyne, which has a triple bond that is stronger and less reactive than the double bond in alkenes. C3H8 (propane) is an alkane, which typically does not react readily with bromine under normal conditions. C2H4 (ethene) is also an alkene, but its symmetrical nature makes it slightly less reactive towards bromine compared to unsymmetrical alkenes like propene.
