This chapter explains the mechanism, stereochemistry, and reactivity of epoxidation reactions, as well as the common reagents and methods used for this transformation.

For example, in the reaction between ethene and hydrogen bromide, one of the two bonds between the two carbon atoms breaks. That bond is simply a pair of electrons. Those electrons move to form a new bond with the hydrogen from the HBr. At the same time the pair of electrons in the hydrogen-bromine bond moves down on to the bromine atom.If your examiners want you to show the transition state, draw the mechanism like this: The reaction of tertiary halogenoalkanes with hydroxide ions.

The key difference between the S N 2 and E2 reactions is that the nucleophile in the S N 2 mechanism attacks the carbon connected to the leaving group (ɑ-carbon) while in E2, the base attacks one of the β-hydrogens. The result is a replacement of the leaving group with a nucleophile, in the S N 2, and a newly-formed π bond in the E2 reaction.

The S N 1 mechanism. A second model for a nucleophilic substitution reaction is called the ' dissociative', or ' SN1' mechanism: in this picture, the C-X bond breaks first, before the nucleophile approaches: This results in the formation of a carbocation: because the central carbon has only three bonds, it bears a formal charge of +1.

So we have a benzylic carbocation in our mechanism. Let me just go ahead and draw that in here.The SN1 Reaction Mechanism. There are two important classes of nucleophilic substitution mechanisms – the SN1 and SN2 mechanisms.; The SN1 mechanism is distinct from the SN2 in several different ways. The reaction is fastest for tertiary alkyl halides and slowest for primary (and methyl) halides The rate law is …Zaitsev’s rule is an empirical rule used to predict the major products of elimination reactions. It states that in an elimination reaction the major product is the more stable alkene with the more highly substituted double bond. This situation is illustrated by the 2-bromobutane and 2-bromo-2,3-dimethylbutane elimination examples given below.
