Give only the major organic products, starting materials or conditions for the following reactions. If more than one isomer is possible make sure to clearly indicate both structures. Be sure to indicate the correct stereochemistry of the products (using dashes and wedges or cis/trans) where needed. Write "NR" if no reaction occurs.
In the substitution reactions below, draw the major product in the box provided and indicate in the small box whether the reaction is SN1, SN2, or neither. Be sure to show all stereochemistry. If more than one enantiomer is produced, write "+Enant" in the box with the product. [10] Product SN1/SN2/Neither NaCN Br DMSO NaOEt EtOH Br NaOMe MeOH NaOH Expensive Acetonitrile CH,Br DMF Nat
For each of the reactions supply the missing final major product(s) in the boxes provided. Clearly show stereochemisty where appropriate. If a reaction produces a mixture of enantiomers draw both. Supply the name of the mechanism (Sn1, Sn2, E1, E2) by which the requested reaction occurs by. MeOH Mechanism Br KCN DMSO Mechanism

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.
