CНз NBS, CCI4, hv lintermediate product(s) Hас Give all resonance structures of the allylic radical intermediate that arise from reaction above. 2. All allylic C-H on the molecule are equivalent so only show the two resonance structures arising from one C-H bond reacting. 3. Are the resonance structures above equivalent or non-equivalent? Think about the degree of the atom where the radical (the dot) is. Give all the products expected from the reaction above. 4.

2-Bromo-2-methylbutane undergoes an E1 elimination reaction in
the presence of ethanol. In the next reaction only one of the
possible products is represented. Although the product shown is not
the major product of the reaction, notice that there is more than
one way it can be produced. Complete the mechanism and draw the
missing substances.
Draw all missing reactants and/or products in the appropriate
boxes by placing atoms on the grid and connecting them with bonds,
including charges where needed....

The reactants are already given in step 1; you need to start by adding curved arrow(s) to the reactants. For each remaining step, draw all species regardless of if they are involved in that step or not. Also, include electrons and charges where necessary.
