- With the catalyst AlCl3 present, which reactant is needed to convert benzene to ethylbenzene?arrow_forwardA student added bromine solution to a hydrocarbon sample that contained an isomer of C6H12 (E) in the absence of light. After shaking the sample, the student noticed that the colour of the bromine solution changed from orange to colourless. Use the following information to answer the question 6. An interpretation that could be made from the student's observations is that the hydrocarbon sample isi and the IUPAC name of the sample could be ii .
