  2. Haloalkane - Wikipedia

    en.wikipedia.org/wiki/Haloalkane

    In primary (1°) haloalkanes, the carbon that carries the halogen atom is only attached to one other alkyl group. An example is chloroethane (CH 3 CH 2 Cl). In secondary (2°) haloalkanes, the carbon that carries the halogen atom has two C–C bonds. In tertiary (3°) haloalkanes, the carbon that carries the halogen atom has three C–C bonds.

  3. IUPAC nomenclature of organic chemistry - Wikipedia

    en.wikipedia.org/wiki/IUPAC_nomenclature_of...

    In haloalkanes and haloarenes (R−X), Halogen functional groups are prefixed with the bonding position and take the form of fluoro-, chloro-, bromo-, iodo-, etc., depending on the halogen. Multiple groups are dichloro-, trichloro-, etc., and dissimilar groups are ordered alphabetically as before. For example, CHCl 3 is

  4. SN1 reaction - Wikipedia

    en.wikipedia.org/wiki/SN1_reaction

    An example of a reaction taking place with an S N 1 reaction mechanism is the hydrolysis of tert-butyl bromide forming tert-butanol: This S N 1 reaction takes place in three steps: Formation of a tert -butyl carbocation by separation of a leaving group (a bromide anion) from the carbon atom: this step is slow.

  5. Secondary (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Secondary_(chemistry)

    Secondary is a term used in organic chemistry to classify various types of compounds (e. g. alcohols, alkyl halides, amines) or reactive intermediates (e. g. alkyl radicals, carbocations). An atom is considered secondary if it has two 'R' Groups attached to it. [1] An 'R' group is a carbon containing group such as a methyl (CH 3).

  6. Functional group - Wikipedia

    en.wikipedia.org/wiki/Functional_group

    Haloalkanes are a class of molecule that is defined by a carbon–halogen bond. This bond can be relatively weak (in the case of an iodoalkane) or quite stable (as in the case of a fluoroalkane). In general, with the exception of fluorinated compounds, haloalkanes readily undergo nucleophilic substitution reactions or elimination reactions. The ...

    en.wikipedia.org/wiki/Free-radical_halogenation

    tertiary (5) > secondary (3.8) > primary (1). Thus any single chlorination step slightly favors substitution at the carbon already most substituted. The rates are generally constant across reactions and predict product distributions with relatively high accuracy. [3] [4] For example, 2-methyl butane ((CH 3) 2 CHCH 2 CH 3) exhibits the following ...

  9. Halocarbon - Wikipedia

    en.wikipedia.org/wiki/Halocarbon

    Examples of organohalogens-chlorides. Halocarbons are typically classified in the same ways as the similarly structured organic compounds that have hydrogen atoms occupying the molecular sites of the halogen atoms in halocarbons. Among the chemical families are: [2] haloalkanes—compounds with carbon atoms linked by single bonds
