  2. Bromocyclopentane - Wikipedia

    en.wikipedia.org/wiki/Bromocyclopentane

    Bromocyclopentane is a derivative of cyclopentane, an alkyl halide with the chemical formula C 5 H 9 Br. It is a colorless to light yellow liquid at standard temperature and pressure . Uses

  3. SNi - Wikipedia

    en.wikipedia.org/wiki/SNi

    In chemistry, S N i (substitution nucleophilic internal) refers to a specific, regio-selective but not often encountered reaction mechanism for nucleophilic aliphatic substitution.

  4. Arrow pushing - Wikipedia

    en.wikipedia.org/wiki/Arrow_pushing

    Arrow pushing or electron pushing is a technique used to describe the progression of organic chemistry reaction mechanisms. [1] It was first developed by Sir Robert Robinson.In using arrow pushing, "curved arrows" or "curly arrows" are drawn on the structural formulae of reactants in a chemical equation to show the reaction mechanism.

  5. Associative substitution - Wikipedia

    en.wikipedia.org/wiki/Associative_substitution

    The terminology is typically applied to organometallic and coordination complexes, but resembles the Sn2 mechanism in organic chemistry. The opposite pathway is dissociative substitution, being analogous to the Sn1 pathway. Intermediate pathways exist between the pure associative and pure dissociative pathways, these are called interchange ...

    This book contains predicted electron configurations for the elements up to 172, as well as 184, based on relativistic Dirac–Fock calculations by B. Fricke in Fricke, B. (1975). Dunitz, J. D. (ed.). "Superheavy elements a prediction of their chemical and physical properties". Structure and Bonding. 21. Berlin: Springer-Verlag: 89– 144.

  7. Electron configuration - Wikipedia

    en.wikipedia.org/wiki/Electron_configuration

    In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. [1] For example, the electron configuration of the neon atom is 1s 2 2s 2 2p 6 , meaning that the 1s, 2s, and 2p subshells are occupied by two, two, and six ...

  8. Michaelis–Arbuzov reaction - Wikipedia

    en.wikipedia.org/wiki/Michaelis–Arbuzov_reaction

    The mechanism of the Michaelis–Arbuzov reaction. The Michaelis–Arbuzov reaction is initiated with the S N 2 attack of the nucleophilic phosphorus species (1 - A phosphite) with the electrophilic alkyl halide (2) to give a phosphonium salt as an intermediate (3).

  9. SN1 reaction - Wikipedia

    en.wikipedia.org/wiki/SN1_reaction

    The carbocation intermediate formed in the reaction's rate determining step (RDS) is an sp 2 hybridized carbon with trigonal planar molecular geometry. This allows two different ways for the nucleophilic attack, one on either side of the planar molecule.
