  2. Tertiary carbon - Wikipedia

    en.wikipedia.org/wiki/Tertiary_carbon

    A tertiary carbon atom is a carbon atom bound to three other carbon atoms. [1] For this reason, tertiary carbon atoms are found only in hydrocarbons containing at least four carbon atoms. They are called saturated hydrocarbons because they only contain carbon-carbon single bonds. [2] Tertiary carbons have a hybridization of sp3. Tertiary carbon ...

  3. Alkyl group - Wikipedia

    en.wikipedia.org/wiki/Alkyl_group

    In addition, each position on an alkyl chain can be described according to how many other carbon atoms are attached to it. The terms primary, secondary, tertiary, and quaternary refer to a carbon attached to one, two, three, or four other carbons respectively.

  4. Secondary carbon - Wikipedia

    en.wikipedia.org/wiki/Secondary_carbon

    A secondary carbon is a carbon atom bound to two other carbon atoms and has sp3 hybridization. [1] For this reason, ... primary carbon: secondary carbon: tertiary carbon:

  5. Carbon-13 nuclear magnetic resonance - Wikipedia

    en.wikipedia.org/wiki/Carbon-13_nuclear_magnetic...

    Carbon-13 (C13) nuclear magnetic resonance ... (DEPT) [11] is an NMR method used for determining the presence of primary, secondary and tertiary carbon atoms.

  6. Carbon–carbon bond - Wikipedia

    en.wikipedia.org/wiki/Carboncarbon_bond

    A primary carbon has one carbon neighbor. A secondary carbon has two carbon neighbors. A tertiary carbon has three carbon neighbors. A quaternary carbon has four carbon neighbors. In "structurally complex organic molecules", it is the three-dimensional orientation of the carboncarbon bonds at quaternary loci which dictates the shape of the ...

  7. Primary carbon - Wikipedia

    en.wikipedia.org/wiki/Primary_carbon

    In organic chemistry, a primary carbon is a carbon atom which is bound to only one other carbon atom. [1] It is thus at the end of a carbon chain . In case of an alkane , three hydrogen atoms are bound to a primary carbon (see propane in the figure on the right).

  8. 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 ]

  9. Alcohol (chemistry) - Wikipedia

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

    Alcohols are then classified into primary, secondary (sec-, s-), and tertiary (tert-, t-), based upon the number of carbon atoms connected to the carbon atom that bears the hydroxyl functional group. The respective numeric shorthands 1°, 2°, and 3° are sometimes used in informal settings. [23] The primary alcohols have general formulas RCH 2 OH.
