  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

    The E1cB mechanism is just one of three types of elimination reaction. The other two elimination reactions are E1 and E2 reactions. Although the mechanisms are similar, they vary in the timing of the deprotonation of the α-carbon and the loss of the leaving group. E1 stands for unimolecular elimination, and E2 stands for bimolecular elimination.

  4. Evelyn effect - Wikipedia

    en.wikipedia.org/wiki/Evelyn_effect

    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. For these two reactions, there are 3 possible products, 3-methyl ...

  5. 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]

  6. Reaction intermediate - Wikipedia

    en.wikipedia.org/wiki/Reaction_intermediate

    E1 and E2 are two different mechanisms for elimination reactions, and E1 involves a carbocation intermediate. In E1, a leaving group detaches from a carbon to form a carbocation reaction intermediate. Then, a solvent removes a proton, but the electrons used to form the proton bond form a pi bond, as shown in the pictured reaction on the right. [4]

  7. Maxine is usually so happy and smiley, so it's clear that the outfit dad put on her is what's making her so upset. I cracked up when he asked if she liked it, and she looked at him like he was ...

  8. Dehydrohalogenation - Wikipedia

    en.wikipedia.org/wiki/Dehydrohalogenation

    CH 2 Cl-CH 2 Cl → CH 2 =CHCl + HCl. The resulting HCl can be reused in oxychlorination reaction. Thermally induced dehydrofluorinations are employed in the production of fluoroolefins and hydrofluoroolefins. One example is the preparation of 1,2,3,3,3-pentafluoropropene from 1,1,2,3,3,3-hexafluoropropane: CF 2 HCH(F)CF 3 → CHF=C(F)CF 3 + HF
