    en.wikipedia.org/wiki/Homoconjugation

    In organic chemistry, homoconjugation is a type of conjugated system where two π-systems are separated by one non-conjugating group. See Conjugated system#Mechanism . Topics referred to by the same term

  3. Conjugate (acid-base theory) - Wikipedia

    en.wikipedia.org/wiki/Conjugate_(acid-base_theory)

    One use of conjugate acids and bases lies in buffering systems, which include a buffer solution. In a buffer, a weak acid and its conjugate base (in the form of a salt), or a weak base and its conjugate acid, are used in order to limit the pH change during a titration process. Buffers have both organic and non-organic chemical applications.

    en.wikipedia.org/wiki/Conjugated_system

    Cinnamaldehyde is a naturally-occurring compound that has a conjugated system penta-1,3-diene is a molecule with a conjugated system Diazomethane conjugated pi-system. In theoretical chemistry, a conjugated system is a system of connected p-orbitals with delocalized electrons in a molecule, which in general lowers the overall energy of the molecule and increases stability.

    In chemistry, azide (/ ˈ eɪ z aɪ d /, AY-zyd) is a linear, polyatomic anion with the formula N − 3 and structure − N=N + =N −.It is the conjugate base of hydrazoic acid HN 3. Organic azides are organic compounds with the formula RN 3, containing the azide functional group. [1]

  6. Gilman reagent - Wikipedia

    en.wikipedia.org/wiki/Gilman_reagent

    A conjugated 1,4 addition using a Gilman reagent with an arbitrary R group. These reagents are useful because, unlike related Grignard reagents and organolithium reagents, they react with organic halides to replace the halide group with an R group (the Corey–House reaction). Such displacement reactions allow for the synthesis of complex ...

  9. Base (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Base_(chemistry)

    Depending on a solid surface's ability to successfully form a conjugate base by absorbing an electrically neutral acid, basic strength of the surface is determined. [15] The "number of basic sites per unit surface area of the solid" is used to express how much basic strength is found on a solid base catalyst. [ 15 ]
