REACTIONS OF HYDROCARBONS Professor has assigned the analysis of unknown hydrocarbon samples to Eoteng Mabutiogting based on their reaction profile. The summary of the observed reactions are tabulated below along with the possible structures of the samples. Identify each unknown sample by matching the respective reactionprofle with the given structures. Name each structures then briefly explain the reason for your answer. Sample Brz in CCl.
