Question

4. Give the mechanistic symbol(s) (SNI. SN2, E1, E2) that is most consistent with each of the following statements. a. Methyl halides react with sodium cthoxide in ethanol only by this mechanism. b. Alkyl iodides react faster than alkyl bromides in reactions that proceed by these mechanisms. c. Results in the largest amount of racemization of an optically active alkyl halide. d. These reaction mechanisms are the ones mostly likely to have been involved when the products are found to have a different carbon skeleton from the substrate. e. These reaction mechanisms represent concerted processes 1. Reactions following these mechanisms will proceed faster in acetone than water 8. Zaitsev's rule allows one to deduce something about the structure of the products formed for these reactions,

Answer 1

4. a) S. 2 o . all-O-ezte an-o-ehf Chort & Ott sul. and Sw2 Jodide is better leaving o 1. group them kromites: SN! Mosca In sal reaction first step is generation of Carbocction intermediate and which is planar. Due to this blanar intermediate optically active compound looses its optical activity. d) El and E2 This is becan - from an alkane - in Ei reactent and to I reachin allone genereted, @ & Sw? and Ez SN 2 and Sn' reaction. In both swt and Sul reactions . polar, a protic solvent. we need
