    Sodium amide, commonly called sodamide (systematic name sodium azanide), is the inorganic compound with the formula NaNH 2.It is a salt composed of the sodium cation and the azanide anion.

  3. Nucleophile - Wikipedia

    en.wikipedia.org/wiki/Nucleophile

    The constant s is defined as 1 with 2-methyl-1-pentene as the nucleophile. Many of the constants have been derived from reaction of so-called benzhydrylium ions as the electrophiles: [10] and a diverse collection of π-nucleophiles: . Typical E values are +6.2 for R = chlorine, +5.90 for R = hydrogen, 0 for R = methoxy and −7.02 for R ...

  4. Nucleophilic substitution - Wikipedia

    en.wikipedia.org/wiki/Nucleophilic_substitution

    A graph showing the relative reactivities of the different alkyl halides towards S N 1 and S N 2 reactions (also see Table 1). In 1935, Edward D. Hughes and Sir Christopher Ingold studied nucleophilic substitution reactions of alkyl halides and related compounds. They proposed that there were two main mechanisms at work, both of them competing ...

  5. Non-nucleophilic base - Wikipedia

    en.wikipedia.org/wiki/Non-nucleophilic_base

    As the name suggests, a non-nucleophilic base is a sterically hindered organic base that is a poor nucleophile. Normal bases are also nucleophiles, but often chemists seek the proton-removing ability of a base without any other functions.

    In chemistry, a nucleofuge (from nucleo- 'atomic nucleus' and fuge 'to run away/escape') is a leaving group which retains the lone pair of electrons from its previous bond with another species.

  8. Arrow pushing - Wikipedia

    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.
