A 1.52 M solution of (R)-2-butanol is mixed with an equal volume of a 0.760 M solution of racemic 2-butanol, and the resulting
solution is analyzed in a sample container that is 1 dm long. What observed rotation is expected? The specific rotation of
(R)-2-butanol is -13.9 degrees mL g-¹ dm¯¹.

A student has isolated a chiral alkyl halide (shown below) with a specific rotation of [a] =
+22.1°. The student decided to store the compound in the solvent MeOH overnight.
However, reanalysis of the alkyl halide showed a new chemical formula of C1H160 with
a specific rotation of [a] = 0°. Suggest a mechanism to justify these results.

Thank you so much!arrow_forward3.arrow_forwardA graduate student was studying enzymatic reductions of cyclohexanones when she encountered some interesting chemistry. When she used an enzyme and NADPH to reduce the following ketone, she was surprised to find that the product was optically active. She carefully repurified the product so that no enzyme, NADPH, or other contaminants were present. Still, the product was optically active. Does the product have any asymmetric carbon atoms or other stereocenters?arrow_forward
