  2. Aliphatic compound - Wikipedia

    en.wikipedia.org/wiki/Aliphatic_compound

    Aliphatic compounds can be saturated, joined by single bonds (), or unsaturated, with double bonds or triple bonds ().If other elements (heteroatoms) are bound to the carbon chain, the most common being oxygen, nitrogen, sulfur, and chlorine, it is no longer a hydrocarbon, and therefore no longer an aliphatic compound.

  3. Hydrazines - Wikipedia

    en.wikipedia.org/wiki/Hydrazines

    Hydrazines (R 2 N−NR 2) are a class of chemical compounds with two nitrogen atoms linked via a covalent bond and which carry from one up to four alkyl or aryl substituents. . Hydrazines can be considered as derivatives of the inorganic hydrazine (H 2 N−NH 2), in which one or more hydrogen atoms have been replaced by hydrocarbon grou

  4. Organic chemistry - Wikipedia

    en.wikipedia.org/wiki/Organic_chemistry

    A functional group is a molecular module, and the reactivity of that functional group is assumed, within limits, to be the same in a variety of molecules. Functional groups can have a decisive influence on the chemical and physical properties of organic compounds. Molecules are classified based on their functional groups.

  5. Aldehyde - Wikipedia

    en.wikipedia.org/wiki/Aldehyde

    A dialdehyde is an organic chemical compound with two aldehyde groups. The nomenclature of dialdehydes have the ending -dial or sometimes -dialdehyde. Short aliphatic dialdehydes are sometimes named after the diacid from which they can be derived. An example is butanedial, which is also called succinaldehyde (from succinic acid).

  6. Bonding in solids - Wikipedia

    en.wikipedia.org/wiki/Bonding_in_solids

    Covalent and ionic bonding form a continuum, with ionic character increasing with increasing difference in the electronegativity of the participating atoms. Covalent bonding corresponds to sharing of a pair of electrons between two atoms of essentially equal electronegativity (for example, C–C and C–H bonds in aliphatic hydrocarbons).

  7. Saturated and unsaturated compounds - Wikipedia

    en.wikipedia.org/wiki/Saturated_and_unsaturated...

    A saturated compound is a chemical compound (or ion) that resists addition reactions, such as hydrogenation, oxidative addition, and binding of a Lewis base. The term is used in many contexts and for many classes of chemical compounds. Overall, saturated compounds are less reactive than unsaturated compounds.

  8. Hydroxy group - Wikipedia

    en.wikipedia.org/wiki/Hydroxy_group

    Representation of an organic compound hydroxy group, where R represents a hydrocarbon or other organic moiety, the red and grey spheres represent oxygen and hydrogen atoms respectively, and the rod-like connections between these, covalent chemical bonds.

  9. Carboxylic acid - Wikipedia

    en.wikipedia.org/wiki/Carboxylic_acid

    In the Barbier–Wieland degradation, a carboxylic acid on an aliphatic chain having a simple methylene bridge at the alpha position can have the chain shortened by one carbon. The inverse procedure is the Arndt–Eistert synthesis , where an acid is converted into acyl halide, which is then reacted with diazomethane to give one additional ...
