  2. 2-Chlorobutane - Wikipedia

    en.wikipedia.org/wiki/2-Chlorobutane

    This is because 2-chlorobutane possesses two different sets of β-hydrogens at the first and third carbons respectively, resulting in 1-butene or 2-butene. It is important to note that as a secondary alkyl halide, both E2 and Sn2 reactions are equally likely when reacting with a substance that can act as both a base and a nucleophile.

  3. Isomeric shift - Wikipedia

    en.wikipedia.org/wiki/Isomeric_shift

    The Mössbauer isomeric shift is the shift seen in gamma-ray spectroscopy when one compares two different nuclear isomeric states in two different physical, chemical or biological environments, and is due to the combined effect of the recoil-free Mössbauer transition between the two nuclear isomeric states and the transition between two atomic ...

  4. Isomerase - Wikipedia

    en.wikipedia.org/wiki/Isomerase

    Isomers themselves exist in many varieties but can generally be classified as structural isomers or stereoisomers. Structural isomers have a different ordering of bonds and/or different bond connectivity from one another, as in the case of hexane and its four other isomeric forms ( 2-methylpentane , 3-methylpentane , 2,2-dimethylbutane , and 2 ...

  5. Isomer - Wikipedia

    en.wikipedia.org/wiki/Isomer

    Isomers do not necessarily share similar chemical or physical properties. Two main forms of isomerism are structural (or constitutional) isomerism, in which bonds between the atoms differ; and stereoisomerism (or spatial isomerism), in which the bonds are the same but the relative positions of the atoms differ. Isomeric relationships form a ...

  6. Isomerization - Wikipedia

    en.wikipedia.org/wiki/Isomerization

    The compound with the formula (C 5 H 5) 2 Fe 2 (CO) 4 exists as three isomers in solution. In one isomer the CO ligands are terminal. When a pair of CO are bridging, cis and trans isomers are possible depending on the location of the C 5 H 5 groups. [7] Another example in organometallic chemistry is the linkage isomerization of ...

  7. Cis–trans isomerism - Wikipedia

    en.wikipedia.org/wiki/Cis–trans_isomerism

    (Here M is a metal atom, and X and Y are two different types of ligands.) In the cis isomer, the two Y ligands are adjacent to each other at 90°, as is true for the two chlorine atoms shown in green in cis-[Co(NH 3) 4 Cl 2] +, at left. In the trans isomer shown at right, the two Cl atoms are on opposite sides of the central Co atom.

  8. Structural isomer - Wikipedia

    en.wikipedia.org/wiki/Structural_isomer

    In contrast, 1-propanol and 2-propanol are structural isomers, but not functional isomers, since they have the same significant functional group (the hydroxyl –OH) and are both alcohols. Besides the different chemistry, functional isomers typically have very different infrared spectra. The infrared spectrum is largely determined by the ...

  9. C5H10 - Wikipedia

    en.wikipedia.org/wiki/C5H10

    Isomers with the molecular formula C 5 H 10 with CAS numbers. C 5 H 10 is the molecular formula of 13 hydrocarbon isomers (represented by their CAS numbers on the chart). They can be divided into cycloalkanes and alkenes.
