Any explanations would be greatly appreciated. This wasn't covered
very well so I'm trying to understand it.
(1) Radical bromination- predict the structure of the major and minor products in the overall reaction given below. Provide a mechanism leading to each, using appropriate curved arrow notation, and a termination for your MAJOR and MINOR product selection. Clearly label the initiation, propagation and steps.

need help with 14-21
Stereochemistry of the Su2 reaction In the Sn2 reaction the tetrahedral carbon center is inverted. We describe the mechanism as nudeophilic (Nuc) back side attack; the leaving group (LG) is leav ing from the front side. Generally, the LG and the Nucare electron rich so it would be unfavorable for them to react from the same side (charge repuls ion). The geometry of the carbon at the transition state is trigonal planar. 14) Label the 2-bromobuta...

10. Consider the three reactions shown below. For each reaction t o 1. Determine whether each of the reactions proceeds via a concerted or a step-wise mechanism. 2. For each concerted reaction, draw the structure of the transition state and label it as transition state (TS). 3. For each step-wise reaction, draw the structure of the most stable intermediate and label it as intermediate. Hint: On the exam, you will need to be able to draw...
