Key Questions

  • Answer:

    A common reaction mechanisme in organic chemistry

    Explanation:

    An #S_n2# reaction, S-ubstitution n-ucleophilic bi-molecular, is a reaction where the bond in a substrate is broken and a new formed simultaneously (in only one step). A #S_n2# reaction could look like this:

    This all happens in one step. The [ ] is an intermediate.
    Note a change in stereochemistry, from an S-configuration carbon to an R-configuration carbon

  • Nucleophilic substitution is the reaction of an electron pair donor (the nucleophile) with an electron pair acceptor (the electrophile).

    The most general form for the reaction may be given as

    Nuc: + R-LG → R-Nuc + LG:

    The electron pair (:) from the nucleophile(Nuc) attacks the substrate (R-LG) forming a new bond, while the leaving group (LG) departs with an electron pair.
