  2. Alkyl group - Wikipedia

    en.wikipedia.org/wiki/Alkyl_group

    If there is more than one of the same alkyl group attached to a chain, then the prefixes are used on the alkyl groups to indicate multiples (i.e., di, tri, tetra, etc.) This compound is known as 2,3,3-trimethylpentane. Here three identical alkyl groups attached to carbon atoms 2, 3, and 3.

  3. Functional group - Wikipedia

    en.wikipedia.org/wiki/Functional_group

    The atoms in a functional group are linked to each other and to the rest of the molecule by covalent bonds. For repeating units of polymers, functional groups attach to their nonpolar core of carbon atoms and thus add chemical character to carbon chains. Functional groups can also be charged, e.g. in carboxylate salts (−COO −), which turns ...

  4. Pendant group - Wikipedia

    en.wikipedia.org/wiki/Pendant_group

    For example, the phenyl groups are the pendant groups on a polystyrene chain. Large, bulky pendant groups such as adamantyl usually raise the glass transition temperature (T g) of a polymer by preventing the chains from sliding past each other easily. Short alkyl pendant groups may lower the T g by a lubricant effect.

  6. Alk- - Wikipedia

    en.wikipedia.org/wiki/Alk-

    Some examples include: meth- (1 carbon) eth- (2 carbons) prop- (3 carbons) but- (4 carbons) pent- (5 carbons) hex- (6 carbons) Alkyl group prefixes: These prefixes are used to name alkyl groups (chains of carbon atoms) that are attached to another molecule. They are formed by adding the suffix "-yl" to the hydrocarbon prefix.

  7. Side chain - Wikipedia

    en.wikipedia.org/wiki/Side_chain

    The side chain is a hydrocarbon branching element of a molecule that is attached to a larger hydrocarbon backbone. It is one factor in determining a molecule's properties and reactivity. [2] A side chain is also known as a pendant chain, but a pendant group (side group) has a different definition.

  8. Substituent - Wikipedia

    en.wikipedia.org/wiki/Substituent

    In organic chemistry, a substituent is one or a group of atoms that replaces (one or more) atoms, thereby becoming a moiety in the resultant (new) molecule. [1] ( In organic chemistry and biochemistry, the terms substituent and functional group, as well as side chain and pendant group, are used almost interchangeably to describe those branches from the parent structure, [2] though certain ...

  9. Butyl group - Wikipedia

    en.wikipedia.org/wiki/Butyl_group

    Alkyl radicals are often considered as a series, a progression sequenced by the number of carbon atoms involved. In that progression, Butyl (containing 4 carbon atoms) is the fourth, and the last with preferred IUPAC name derived from its history. The word "butyl" is derived from butyric acid, a four-carbon carboxylic acid found in rancid ...
