  2. Sabatier principle - Wikipedia

    en.wikipedia.org/wiki/Sabatier_principle

    The figure on the right shows a volcano plot for the decomposition of formic acid using different transition metals as catalysts. [5] In this case, the heat of formation (Δ f H) of the metal formate salt was used for the x axis because studies showed that the reaction intermediate was a surface formate. For the y axis, the temperature at which ...

  3. Verkade base - Wikipedia

    en.wikipedia.org/wiki/Verkade_base

    In chemistry, the Verkade base (or Verkade superbase) is a powerful superbase with the formula P(MeNCH 2 CH 2) 3 N. A colorless oil, it is an aminophosphine although its inventor John Verkade called it proazaphosphatrane. The trimethyl derivative or 2,5,8,9-tetraaza-1-phosphabicyclo[3.3.3]undecane is the simplest. [1]

  4. Superbase - Wikipedia

    en.wikipedia.org/wiki/Superbase

    Strong superbases can be designed by utilizing various approaches [7] [8] [9] to stabilize the conjugate acid, up to the theoretical limits of basicity. [ 10 ] Organometallic superbases, sometimes called Lochmann–Schlosser superbases, result from the combination of alkali metal alkoxides and organolithium reagents. [ 11 ]

  5. Transition state theory - Wikipedia

    en.wikipedia.org/wiki/Transition_state_theory

    Figure 1: Reaction coordinate diagram for the bimolecular nucleophilic substitution (S N 2) reaction between bromomethane and the hydroxide anion In chemistry, transition state theory (TST) explains the reaction rates of elementary chemical reactions.

  6. Reaction mechanism - Wikipedia

    en.wikipedia.org/wiki/Reaction_mechanism

    In chemistry, a reaction mechanism is the step by step sequence of elementary reactions by which overall chemical reaction occurs. [1] A chemical mechanism is a theoretical conjecture that tries to describe in detail what takes place at each stage of an overall chemical reaction. The detailed steps of a reaction are not observable in most cases.

  7. Schlosser's base - Wikipedia

    en.wikipedia.org/wiki/Schlosser's_base

    The high reactivity of Schlosser's base is exploited in synthetic organic chemistry for the preparation of organometallic reagents. For example, potassium benzyl can be prepared from toluene using this reagent. Benzene and cis/trans-2-butene are also readily metalated by Schlosser's base. Toluene, benzene, and butenes react only slowly with ...

  8. Activated complex - Wikipedia

    en.wikipedia.org/wiki/Activated_complex

    The transition state, represented by the double dagger symbol represents the exact configuration of atoms that has an equal probability of forming either the reactants or products of the given reaction. [5] The activation energy is the minimum amount of energy to initiate a chemical reaction and form the activated complex. [6]

  9. List of chemistry mnemonics - Wikipedia

    en.wikipedia.org/wiki/List_of_chemistry_mnemonics

    An atom (or ion) whose oxidation number increases in a redox reaction is said to be oxidized (and is called a reducing agent). It is accomplished by loss of one or more electrons. The atom whose oxidation number decreases gains (receives) one or more electrons and is said to be reduced. This relation can be remembered by the following mnemonics.
