What is the likely transition state for this reaction?Question:What is the likely transition state for this reaction? SN2 Reaction:A nucleophilic substitution reaction is of two types: SN1 and SN2. The SN2 reaction takes place in a single step. The formation of the bond as well as the brea...
An important link between theoretical and experimental views of organic reactivity is provided by More O'Ferrall-Jencks diagrams, which are commonly used in empirical discussions of reaction mechanisms and of changes in transition-state structure. We have performed semiempirical AM1 molecular-orbital ...
The solvolyses of t-butyl chloride, benzyl chloride, and p-chlorobenzyl chloride represented a gradation of reaction type between SN1 and SN2 and the transition state partial molal volume behavior was found to be distinctly different in each case and in agreement with the mechanistic classification...
Draw the mechanism and the transition state of the primary reaction mechanism of the following reaction? Nucleophilic Substitution Reaction: Suppose an alkyl halide say R-X is treated with a nucleophile (Nu−). The nucleophile will attack the electrophilic carbon...
Smaller r+ value for α-CF3-2-phenylethyl system, of which transition state is more destabilized than that of β-CF3-2-phenylethyl system, is quite contrast to the increase in r+ by the destabilization of carbocation intermediate in benzylic SN1 solvolyses. The transition structures of α-...

A distinct geometrical preference is associated with the change in mechanism: in a tight SN2 transition state the nitrogen lone pair is turned to avoid repulsive interaction, while it parallels the reaction coordinate in a loose, SN1-like transition state....
