A student performs a laboratory test on an unknown organic compound. When bromine water is added, the orange-brown colour persists and does not decolourise. Which statement best describes the unknown compound?
A student performs a test on three unknown hydrocarbon samples: X, Y, and Z. The samples are exposed to bromine water at room temperature. Sample X decolourizes the bromine water quickly from orange to colourless. Sample Y shows no colour change. Sample Z decolourizes the bromine water, but much more slowly than X. Which statement correctly identifies the hydrocarbon types?
Describe the results of the bromine water test when applied separately to hexane (an alkane) and hex-1-ene (an alkene).
