  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. E1cB-elimination reaction - Wikipedia

    en.wikipedia.org/wiki/E1cB-elimination_reaction

    An example of the E1cB reaction mechanism in the degradation of a hemiketal under basic conditions. The E1cB elimination reaction is a type of elimination reaction which occurs under basic conditions, where the hydrogen to be removed is relatively acidic, while the leaving group (such as -OH or -OR) is a relatively poor one.

  4. Evelyn effect - Wikipedia

    en.wikipedia.org/wiki/Evelyn_effect

    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. An E1 reaction is the Ionization of the carbon-halogen bond breaking to give a carbocation intermediate, then the Deprotonation of the carbocation.

  5. SN1 reaction - Wikipedia

    en.wikipedia.org/wiki/SN1_reaction

    If the reaction is performed under warm or hot conditions (which favor an increase in entropy), E1 elimination is likely to predominate, leading to formation of an alkene. At lower temperatures, S N 1 and E1 reactions are competitive reactions and it becomes difficult to favor one over the other. Even if the reaction is performed cold, some ...

  6. Ei mechanism - Wikipedia

    en.wikipedia.org/wiki/Ei_mechanism

    In organic chemistry, the E i mechanism (Elimination Internal/Intramolecular), also known as a thermal syn elimination or a pericyclic syn elimination, is a special type of elimination reaction in which two vicinal (adjacent) substituents on an alkane framework leave simultaneously via a cyclic transition state to form an alkene in a syn elimination. [1]

    The post's caption says, "These 6 States will be banning the purchase of RV’s starting in less than 6 weeks," going on to list California, New York, Oregon, Massachusetts, New Jersey and Washington.

  8. Dehydrohalogenation - Wikipedia

    en.wikipedia.org/wiki/Dehydrohalogenation

    In chemistry, dehydrohalogenation is an elimination reaction which removes a hydrogen halide from a substrate. The reaction is usually associated with the synthesis of alkenes , but it has wider applications.
