Which of the following statements is true concerning the E2 reactions of alkyl fluorides? A)Alkyl fluorides react more readily in E2 reactions than do alkyl iodides. B)The transition state of this E2 reaction resembles a carbanion rather than an alkene. C)The C-F bond is the weakest carbon-halogen bond so S_N2 will always predominate over E2 in the reactions of alkyl fluorides. D)Alkyl fluorides react to form the most stable carbocation intermediate. E)Alkyl fluorides cannot adopt the proper stereochemical alignment for an E2 reaction to occur.

Question

Quizplus · Accepted Answer

The transition state of E2 reactions involving alkyl fluorides resembles a carbanion due to the strong C-F bond, which makes the leaving group less favorable, thus requiring more carbanion character in the transition state.
