Напишите уравнения реакций с которых можно осуществить цепочку превращения веществ : бутан–2-метилпропан–2-бром-2-метилпропан

1) CH3-CH2-CH2-CH3 --(AlCl3)--> CH3-CH-CH3
                                                                  |
                                                                 CH3

                                                               Br
                                                                |
2) CH3-CH-CH3 + Br2 --(свет)--> CH3-C-CH3 + HBr
              |                                                 |
             CH3                                           CH3
