  2. Isomer - Wikipedia

    en.wikipedia.org/wiki/Isomer

    The most common one in nature (myo-inositol) has the hydroxyls on carbons 1, 2, 3 and 5 on the same side of that plane, and can therefore be called cis-1,2,3,5-trans-4,6-cyclohexanehexol. And each of these cis - trans isomers can possibly have stable "chair" or "boat" conformations (although the barriers between these are significantly lower ...

  3. Arene substitution pattern - Wikipedia

    en.wikipedia.org/wiki/Arene_substitution_pattern

    In ortho-substitution, two substituents occupy positions next to each other, which may be numbered 1 and 2.In the diagram, these positions are marked R and ortho.; In meta-substitution, the substituents occupy positions 1 and 3 (corresponding to R and meta in the diagram).

  4. Dihydroxybenzenes - Wikipedia

    en.wikipedia.org/wiki/Dihydroxybenzenes

    All three isomers have the chemical formula C 6 H 6 O 2. Similar to other phenols, the hydroxyl groups on the aromatic ring of a benzenediol are weakly acidic . Each benzenediol can lose an H + from one of the hydroxyls to form a type of phenolate ion.

  5. 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 ...

  6. Isomerase - Wikipedia

    en.wikipedia.org/wiki/Isomerase

    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 2,3-dimethylbutane).

  7. Hydroxy group - Wikipedia

    en.wikipedia.org/wiki/Hydroxy_group

    In chemistry, a hydroxy or hydroxyl group is a functional group with the chemical formula −OH and composed of one oxygen atom covalently bonded to one hydrogen atom. In organic chemistry , alcohols and carboxylic acids contain one or more hydroxy groups.

  8. Syn and anti addition - Wikipedia

    en.wikipedia.org/wiki/Syn_and_anti_addition

    In organic chemistry, syn-and anti-addition are different ways in which substituent molecules can be added to an alkene (R 2 C=CR 2) or alkyne (RC≡CR).The concepts of syn and anti addition are used to characterize the different reactions of organic chemistry by reflecting the stereochemistry of the products in a reaction.

  9. Butanol - Wikipedia

    en.wikipedia.org/wiki/Butanol

    Butanol (also called butyl alcohol) is a four-carbon alcohol with a formula of C 4 H 9 O H, which occurs in five isomeric structures (four structural isomers), from a straight-chain primary alcohol to a branched-chain tertiary alcohol; [1] all are a butyl or isobutyl group linked to a hydroxyl group (sometimes represented as BuOH, sec-BuOH, i-BuOH, and t-BuOH).
