The following 2 molecules were produced from the same starting epoxide, but each results from ring opening under different conditions.
(R)-2-ethoxy-2-methyl-1-butanol and (S)-1-ethoxy-2-methyl-2-butanol
(a) Draw the skeletal structure of the starting material epoxide.
(b) Draw the skeletal structure of the nucleophile that effected the ring opening resulting in the product with the (S)-configuration.
(c) Draw the skeletal structure of the nucleophile that effected the ring opening resulting in the product with the (R)-configuration.
(d) Select the condition under which the (S)-configuration ring opening occurred.
