epoxide - 2023 ARCADIA - Buzzpoints App

Question

This functional group is produced in an asymmetric reaction named for K. Barry Sharpless that employs enantio·pure tartrates. For 10 points each:

[10m] Name this strained functional group, which can also be synthesized by reacting an alkene with a peroxy·acid such as mCPBA.

ANSWER: epoxide [accept oxirane; prompt on ether]

[10h] Sharpless epoxidation exhibits this behavior, in which the enantiomeric excess of the catalyst is not proportional to the enantiomeric excess of the product formed. This behavior can be attributed to the reservoir effect.

ANSWER: non-linear effect [accept NLE]

[10e] A non-linear effect due to the reservoir effect necessarily has a lower value for this quantity, symbolized k. This quantity can have varying units of M over s, 1 over s, or 1 over M times s depending on if a reaction is zero, first, or second-order, respectively.

ANSWER: rate constant [prompt on reaction rate]
