Unformatted text preview: 14. (4 pts) When A and B react in t-BuOH, the following rate expression is observed: -d[ A ]/dt = k[ A ][ B ] Ph A : B : OK OTos What is the most likely mechanism of this reaction? a) E2 b) S N 2 c) E1 d) S N 1 e) it cannot be determined Comments: The rate expression indicated a bimolecular reaction (S N 2 or E2). Elimination cannot take place because there are no hydrogens on carbons directly adjacent to the carbon with the leaving group. Compare: TS4: 65, or PE4A: 10-11, PE4C: 26....
