Provide the full mechanism and draw the final product for the following E2 reaction.

Provide the full mechanism and draw the final product for the following E2 reaction.

a.

Provide the full mechanism and draw the final product for the following E2 reaction.

c.

Show that the (S,S) enantiomer of this (R,R) diastereomer of 1-bromo-1,2-diphenylpropane also undergoes E2 elimination to give the cis diastereomer of the product. (We do not expect these achiral reagents to distinguish between enantiomers.)

Give the expected product(s) of E2 elimination for each reaction. (Hint: Use models!)

(b)

Draw the elimination products for each of the following E2 reactions; if the products can exist as stereoisomers, indicate which stereoisomers are obtained.

a. (2S,3S)-2-chloro-3-methylpentane + high concentration of CH₃O⁻

b. (2S,3R)-2-chloro-3-methylpentane + high concentration of CH₃O⁻
