Draw out the most likely propagation step of these reactions of radicals with hydrocarbons based upon radical stability of the product radical. Then, propose a termination step that would make a likely stable (non-radical) product of the reaction. b) -Br
1. In a Birch reaction, an aromatic compound can be treated with Na/CH3OH, it can also be treated with Li/NH3 and have the same product form. One of the intermediates in the Birch reaction is a radical anion. In the example below, anisole could possibly form a radical anion A or B, then will go into C and D. Li/NH3 A B C D A. With the knowledge you have gained from what we have discussed, which anion A or B is more stable? What is your reasoning? B. Is a Birch reaction and oxidation or reduction? Why?

5. Our textbook gives two reactions that result in anti-Markovnikov additions with alkenes. i. ii. iii. The first is hydroboration forming an anti-Markovnikov Draw the single mechanistic step of the "syn" addition which determines the anti- Markovnikov addition. I The second, the radical addition of HBr to an alkene, has a critical propagation step which determines the addition selectivity. Draw this step below.
How many additional carbons can easily support this radical via resonance (no hydride or methyl shifts)? Enter a number, 0, 1, 2, 3.
17. a. Label the reactive features, highlight the most reactive one, then highlight what it needs. Also, state if the reaction will start to create a carbocation, carbon radical, or carbanion, or will cause loss of aromatic character. If a carbocation, carbon radical, or carbanion starts to develop, label where that will occur. -CH3 with H,SO, b. Use mechanism arrows to illustrate the reaction that occurs. c. If applicable, use stabilization resources to deal with the carbocation, carbon radical, or carbanion that starts to develop during the reaction, and draw the structure of any resonance-stabilized intermediate. d. Continue labeling and diagramming the reaction until you find the major stable product(s). e. Finally, state the stereochemistry of the major product(s) and use either Fisher projection or perspective formula representations to illustrate that stereochemistry.
