  2. Functional group - Wikipedia

    en.wikipedia.org/wiki/Functional_group

    In organic chemistry, a functional group is a substituent or moiety in a molecule that causes the molecule's characteristic chemical reactions. The same functional group will undergo the same or similar chemical reactions regardless of the rest of the molecule's composition. [1][2] This enables systematic prediction of chemical reactions and ...

  3. Aldehyde - Wikipedia

    en.wikipedia.org/wiki/Aldehyde

    Aldehyde structure. In organic chemistry, an aldehyde (/ ˈ æ l d ɪ h aɪ d /) is an organic compound containing a functional group with the structure R−CH=O. [1] The functional group itself (without the "R" side chain) can be referred to as an aldehyde but can also be classified as a formyl group.

  4. 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 ...

  5. α,β-Unsaturated carbonyl compound - Wikipedia

    en.wikipedia.org/wiki/Α,β-Unsaturated_carbonyl...

    α,β-Unsaturated carbonyl compounds featuring a carbonyl conjugated to an alkene that is terminal, or vinylic, contain the acryloyl group (H 2 C =CH−C (= O)−); it is the acyl group derived from acrylic acid. The preferred IUPAC name for the group is prop-2-enoyl, and it is also known as acrylyl or simply (and incorrectly) as acryl.

  6. Alkyl group - Wikipedia

    en.wikipedia.org/wiki/Alkyl_group

    In organic chemistry, an alkyl group is an alkane missing one hydrogen. [1] The term alkyl is intentionally unspecific to include many possible substitutions. An acyclic alkyl has the general formula of −CnH2n+1. A cycloalkyl group is derived from a cycloalkane by removal of a hydrogen atom from a ring and has the general formula −CnH2n−1 ...

  7. Triflate - Wikipedia

    en.wikipedia.org/wiki/Triflate

    Triflate anion. In organic chemistry, triflate (systematic name: trifluoromethanesulfonate), is a functional group with the formula R−OSO2CF3 and structure R−O−S (=O)2−CF3. The triflate group is often represented by −OTf, as opposed to −Tf, which is the triflyl group, R−SO2CF3. For example, n -butyl triflate can be written as ...

  8. Auxochrome - Wikipedia

    en.wikipedia.org/wiki/Auxochrome

    Auxochrome. In organic chemistry, an auxochrome (from Ancient Greek αὐξάνω (auxanō) 'increase' and χρῶμα (chrōma) 'colour') is a group of atoms attached to a chromophore which modifies the ability of that chromophore to absorb light. They themselves fail to produce the colour, but instead intensify the colour of the chromogen ...

  9. Functionality (chemistry) - Wikipedia

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

    Functionality (chemistry) In chemistry, functionality is the presence of functional groups in a molecule. A monofunctional molecule possesses one functional group, a bifunctional (or difunctional) two, a trifunctional three, and so forth. In organic chemistry (and other fields of chemistry), a molecule's functionality has a decisive influence ...
