Unformatted text preview: at the time. 2. Arrange the four hydrocarbons in order of their reactivity toward bromine, most reactive first, and compare your results with your predictions. Write a balanced equation for each reaction and give structures for each free radical intermediate. Arrange the free radicals in order of stability and explain their relative stabilities. Write a complete mechanism for the bromination of toluene. Data and Observations: 1) Isopropyl Benzene immediately cleared 2) ethylbenzene – a minute or so, yellowish 3) Toluene – Several minutes – light orange 4) Tertbutyl - not decolorized – orange Conclusion: Our results of the most reactive begin with isopropyl benzene, continue 1 with ethylbenzene, toluene, and finally tertiary butyl. This reactivity order can be explained by these hydrocarbons reactivity with free radical bromination. The first 3 occur at the benzylic position with the more alkyl groups meaning more electron donating plausibility. 2...
