  2. Hydroxide - Wikipedia

    en.wikipedia.org/wiki/Hydroxide

    R 1 C(O)OR 2 + OH − ⇌ R 1 CO(O)H + − OR 2 ⇌ R 1 CO 2 − + HOR 2. is an example of a hydroxide ion serving as a nucleophile. [52] Early methods for manufacturing soap treated triglycerides from animal fat (the ester) with lye.

  3. Transition metal hydroxide complexes - Wikipedia

    en.wikipedia.org/wiki/Transition_metal_hydroxide...

    L n M−OH + H + ⇌ L n M−OH + 2 where L n is the ligand complement on the metal M. Thus, aquo ligand is a weak acid, of comparable strength to acetic acid (pK a of about 4.8). [6] In principle but not very commonly, metal hydroxides undergo deprotonation, yielding oxo complexes: L n M−OH ⇌ L n M=O − +H +

  4. 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.

  5. Hydroxyl radical - Wikipedia

    en.wikipedia.org/wiki/Hydroxyl_radical

    Skeletal formulae of 1-hydroxy-2-pyridinethione and its tautomer. The hydroxyl radical, • HO, is the neutral form of the hydroxide ion (HO –). Hydroxyl radicals are highly reactive and consequently short-lived; however, they form an important part of radical chemistry.

  6. Alcohol (chemistry) - Wikipedia

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

    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. [ 3 ] [ 4 ] Alcohols range from the simple, like methanol and ethanol , to complex, like sugars and cholesterol .

  7. Metal hydroxide - Wikipedia

    en.wikipedia.org/wiki/Metal_hydroxide

    In chemistry, metal hydroxides are a family of compounds of the form M n+ (OH) n, where M is a metal. They consist of hydroxide (OH −) anions and metallic cations, [1] and are often strong bases. Some metal hydroxides, such as alkali metal hydroxides, ionize completely when dissolved.

  8. Equivalent concentration - Wikipedia

    en.wikipedia.org/wiki/Equivalent_concentration

    In acid-base chemistry, normality is used to express the concentration of hydronium ions (H 3 O +) or hydroxide ions (OH −) in a solution. Here, ⁠ 1 / f eq ⁠ is an integer value. Each solute can produce one or more equivalents of reactive species when dissolved.

  9. Enol - Wikipedia

    en.wikipedia.org/wiki/Enol

    In organic chemistry, enols are a type of Functional group or intermediate in organic chemistry containing a group with the formula C=C(OH) (R = many substituents). The term enol is an abbreviation of alkenol, a portmanteau deriving from "-ene"/"alkene" and the "-ol". Many kinds of enols are known. [1]
