Mini-Spiderweb (16 pts,
2pts/box). Please complete the following reaction spiderweb with
the appropriate starting materials, reagents or products. Pay
attention to stereochemistry, and for product boxes – include only
the major product(s), unless otherwise noted. E1 and Sn1 (5 pts).
The following alkyl halide will undergo both E1 and Sn1 mechanisms
to give a slew of products when exposed to water. Please draw them
all in the box below. Remember to consider rearrangements and
account for all stereoisomers formed.
