  3. SN1 reaction - Wikipedia

    en.wikipedia.org/wiki/SN1_reaction

    An example of a reaction proceeding in a S N 1 fashion is the synthesis of 2,5-dichloro-2,5-dimethylhexane from the corresponding diol with concentrated hydrochloric acid: [8] As the alpha and beta substitutions increase with respect to leaving groups, the reaction is diverted from S N 2 to S N 1.

    This results in S N 1 reactions usually occurring on atoms with at least two carbons bonded to them. [2] A more detailed explanation of this can be found in the main SN1 reaction page. S N 2 reaction mechanism. The S N 2 mechanism has just one step. The attack of the reagent and the expulsion of the leaving group happen simultaneously.

    en.wikipedia.org/wiki/Arrow_pushing

    Arrow pushing or electron pushing is a technique used to describe the progression of organic chemistry reaction mechanisms. [1] It was first developed by Sir Robert Robinson.In using arrow pushing, "curved arrows" or "curly arrows" are drawn on the structural formulae of reactants in a chemical equation to show the reaction mechanism.

    V = z 1 z 2 e 2 /4πaε Where z is the charge number of each species and ε is the vacuum permittivity . A typical value for K E is 0.0202 dm 3 mol −1 for neutral particles at a distance of 200 pm. [ 9 ] The result of the rate law is that at high concentrations of Y, the rate approximates k[M] tot while at low concentrations the result is kK ...

    An aromatic ring can assist in the formation of a carbocationic intermediate called a phenonium ion by delocalising the positive charge. When the following tosylate reacts with acetic acid in solvolysis then rather than a simple S N 2 reaction forming B, a 48:48:4 mixture of A, B (which are enantiomers) and C+D was obtained [2] [3] .
