  2. Elimination reaction - Wikipedia

    en.wikipedia.org/wiki/Elimination_reaction

    Elimination reaction of cyclohexanol to cyclohexene with sulfuric acid and heat [1] An elimination reaction is a type of organic reaction in which two substituents are removed from a molecule in either a one- or two-step mechanism. [2] The one-step mechanism is known as the E2 reaction, and the two-step mechanism is known as the E1 reaction ...

  3. Evelyn effect - Wikipedia

    en.wikipedia.org/wiki/Evelyn_effect

    In general, if more than one alkene can be formed during dehalogenation by an elimination reaction, the more stable alkene is the major product. There are two types of elimination reactions, E1 and E2. An E2 reaction is a One step mechanism in which carbon-hydrogen and carbon-halogen bonds break to form a double bond. C=C Pi bond.

  4. Zaytsev's rule - Wikipedia

    en.wikipedia.org/wiki/Zaytsev's_rule

    More generally, Zaytsev's rule predicts that in an elimination reaction the most substituted product will be the most stable, and therefore the most favored. The rule makes no generalizations about the stereochemistry of the newly formed alkene, but only the regiochemistry of the elimination reaction. While effective at predicting the favored ...

    en.wikipedia.org/wiki/Hughes–Ingold_symbol

    For example, an S N 2 reaction is a substitution reaction ("S") by a nucleophilic process ("N") that is bimolecular ("2" molecular entities involved) in its rate-determining step. By contrast, an E2 reaction is an elimination reaction, an S E 2 reaction involves electrophilic substitution, and an S N 1 reaction is unimolecular.

  6. Ubiquitin-conjugating enzyme - Wikipedia

    en.wikipedia.org/wiki/Ubiquitin-conjugating_enzyme

    Ubiquitin-conjugating enzymes, also known as E2 enzymes and more rarely as ubiquitin-carrier enzymes, perform the second step in the ubiquitination reaction that targets a protein for degradation via the proteasome. The ubiquitination process covalently attaches ubiquitin, a short protein of 76 amino acids, to a lysine residue on the target ...

  8. SN2 reaction - Wikipedia

    en.wikipedia.org/wiki/SN2_reaction

    A common side reaction taking place with S N 2 reactions is E2 elimination: the incoming anion can act as a base rather than as a nucleophile, abstracting a proton and leading to formation of the alkene. This pathway is favored with sterically hindered nucleophiles.

  9. E2 - Wikipedia

    E2 reaction, a type of elimination reaction; Honda E2, one of the predecessors of Honda's ASIMO robot; E2, a communications channel defined in the E-carrier standard; G 2 (mathematics) (old name E2 or E 2), a group
