  2. Isomer - Wikipedia

    en.wikipedia.org/wiki/Isomer

    For example, in the cyclic alcohol inositol (a six-fold alcohol of cyclohexane), the six-carbon cyclic backbone largely prevents the hydroxyl and the hydrogen on each carbon from switching places. Therefore, one has different configurational isomers depending on whether each hydroxyl is on "this side" or "the other side" of the ring's mean plane.

    The red and white balls represent the hydroxyl group (−OH). The three "R"s stand for carbon substituents or hydrogen atoms. [1] In chemistry, an alcohol (from Arabic al-kuḥl 'the kohl'), [2] is a type of organic compound that carries at least one hydroxyl (−OH) functional group bound to a saturated carbon atom.

    Separately, a solution of the lithium salt of (±)-cis-4-benzyloxy-2,3-epoxy-1-butanol (Solution B) was prepared as follows: to a solution of 0.5 g (2.58 mmol) of the epoxy alcohol and 0.90 g (21.4 mmol) of lithium chloride in 10 mL of tetrahydrofuran under argon at −78° was added dropwise 1.65 mL of a solution of n-butyllithium in hexane (1 ...

  5. Cyclohexane-1,2,3,4,5,6-hexol - Wikipedia

    en.wikipedia.org/wiki/Cyclohexane-1,2,3,4,5,6-hexol

    Cyclohexane-1,2,3,4,5,6-hexol is a family of chemical compounds with formula C 6 H 12 O 6, whose molecule consists of a ring of six carbon atoms, each bound to one hydrogen atom and one hydroxyl group (–OH). There are nine stereoisomers, that differ by the position of

  6. 2-Heptanol - Wikipedia

    en.wikipedia.org/wiki/2-Heptanol

    2-Heptanol is a chemical compound which is an isomer of heptanol. It is a secondary alcohol with the hydroxyl on the second carbon of the straight seven-carbon chain. The compound is flammable and irritant, and through inhalation, ingestion or though skin it can enter into the body. [3] 2-Heptanol is chiral, so (R)- and (S)-isomers exist.

  7. Monosaccharide nomenclature - Wikipedia

    en.wikipedia.org/wiki/Monosaccharide_nomenclature

    Two isomers whose molecules are mirror-images of each other are identified by prefixes ' D-' or ' L-', according to the handedness of the chiral carbon atom that is farthest from the carbonyl. In the Fischer projection, that is the second carbon from the bottom; the prefix is ' D -' or ' L -' according to whether the hydroxyl on that carbon ...

  8. Structural isomer - Wikipedia

    Another example is the pair ethanol H 3 C–CH 2 –OH (an alcohol) and dimethyl ether H 3 C–O–CH 2 H (an ether). 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.

  9. 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.
