  2. Organic compound - Wikipedia

    en.wikipedia.org/wiki/Organic_compound

    For example, carbon-containing compounds such as alkanes (e.g. methane CH 4) and its derivatives are universally considered organic, but many others are sometimes considered inorganic, such as halides of carbon without carbon-hydrogen and carbon-carbon bonds (e.g. carbon tetrachloride CCl 4), and certain compounds of carbon with nitrogen and ...

  3. Organic chemistry - Wikipedia

    en.wikipedia.org/wiki/Organic_chemistry

    Some organic compounds, especially symmetrical ones, sublime. A well-known example of a sublimable organic compound is para-dichlorobenzene, the odiferous constituent of modern mothballs. Organic compounds are usually not very stable at temperatures above 300 °C, although some exceptions exist.

  4. Functional group - Wikipedia

    en.wikipedia.org/wiki/Functional_group

    For example, sugar dissolves in water because both share the hydroxyl functional group (−OH) and hydroxyls interact strongly with each other. Plus, when functional groups are more electronegative than atoms they attach to, the functional groups will become polar, and the otherwise nonpolar molecules containing these functional groups become ...

  5. Lipid - Wikipedia

    en.wikipedia.org/wiki/Lipid

    Lipids are a broad group of organic compounds which include fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E and K), monoglycerides, diglycerides, phospholipids, and others. The functions of lipids include storing energy, signaling, and acting as structural components of cell membranes.

  6. Functionality (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Functionality_(Chemistry)

    In organic chemistry, functionality is often used as a synonym for functional group. For example, a hydroxyl group can also be called a HO-function. [1] [2] Functionalisation means the introduction of functional groups, for example the functionalisation of a surface [3] (e.g. silanization for the specific modification of the adhesion of a surface)

  7. Organic matter - Wikipedia

    en.wikipedia.org/wiki/Organic_matter

    Larger molecules of organic matter can be formed from the polymerization of different parts of already broken down matter. [citation needed] The composition of natural organic matter depends on its origin, transformation mode, age, and existing environment, thus its bio-physicochemical functions vary with different environments. [4]

  8. Organic acid - Wikipedia

    en.wikipedia.org/wiki/Organic_acid

    An organic acid is an organic compound with acidic properties. The most common organic acids are the carboxylic acids, whose acidity is associated with their carboxyl group –COOH. Sulfonic acids, containing the group –SO 2 OH, are relatively stronger acids. Alcohols, with –OH, can act as acids but they are usually very weak.
