  2. Organosilicon chemistry - Wikipedia

    en.wikipedia.org/wiki/Organosilicon_chemistry

    Organosilicon chemistry is the study of organometallic compounds containing carbon–silicon bonds, to which they are called organosilicon compounds. Most organosilicon compounds are similar to the ordinary organic compounds, being colourless, flammable, hydrophobic, and stable to air.

  3. 1-Ethyl-3- (3-dimethylaminopropyl)carbodiimide - Wikipedia

    en.wikipedia.org/wiki/1-Ethyl-3-(3-dimethylamino...

    It is generally used as a carboxyl activating agent for the coupling of primary amines to yield amide bonds. While other carbodiimides like dicyclohexylcarbodiimide (DCC) or diisopropylcarbodiimide (DIC) are also employed for this purpose, EDC has the advantage that the urea byproduct formed (often challenging to remove in the case of DCC or ...

  4. Coupling reaction - Wikipedia

    en.wikipedia.org/wiki/Coupling_reaction

    In organic chemistry, a coupling reaction is a type of reaction in which two reactant molecules are bonded together. Such reactions often require the aid of a metal catalyst.

  5. Cyclic compound - Wikipedia

    en.wikipedia.org/wiki/Cyclic_compound

    [citation needed] The term macrocycle is used when a ring-containing compound has a ring of 12 or more atoms. [6] [7] The term polycyclic is used when more than one ring appears in a single molecule. Naphthalene is formally a polycyclic compound, but is more specifically named as a bicyclic compound. Several examples of macrocyclic and ...

  6. Heterocyclic compound - Wikipedia

    en.wikipedia.org/wiki/Heterocyclic_compound

    Heterocyclic organic chemistry is the branch of organic chemistry dealing with the synthesis, properties, and applications of organic heterocycles. [2] Examples of heterocyclic compounds include all of the nucleic acids, the majority of drugs, most biomass (cellulose and related materials), and many natural and synthetic dyes. More than half of ...

  7. Life insurance - Wikipedia

    en.wikipedia.org/wiki/Life_insurance

    Permanent life insurance is life insurance that covers the remaining lifetime of the insured. A permanent insurance policy accumulates a cash value up to its date of maturation. The owner can access the money in the cash value by withdrawing money, borrowing the cash value, or surrendering the policy and receiving the surrender value.

  8. Bicyclic molecule - Wikipedia

    en.wikipedia.org/wiki/Bicyclic_molecule

    An example of a spirocyclic compound is the photochromic switch spiropyran. In fused/condensed [ 5 ] bicyclic compounds , two rings share two adjacent atoms. In other words, the rings share one covalent bond, i.e. the bridgehead atoms are directly connected ( e.g. α-thujene and decalin ).

    Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
