  2. 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 −C n H 2n+1. A cycloalkyl group is derived from a cycloalkane by removal of a hydrogen atom from a ring and has the general formula −C n H ...

  3. Alkene - Wikipedia

    en.wikipedia.org/wiki/Alkene

    Find the longest carbon chain in the molecule. If that chain does not contain the double bond, name the compound according to the alkane naming rules. Otherwise: Number the carbons in that chain starting from the end that is closest to the double bond. Define the location k of the double bond as being the number of its first carbon.

  4. C5H10 - Wikipedia

    en.wikipedia.org/wiki/C5H10

    Isomers with the molecular formula C 5 H 10 with CAS numbers. C 5 H 10 is the molecular formula of 13 hydrocarbon isomers (represented by their CAS numbers on the chart). They can be divided into cycloalkanes and alkenes.

  5. IUPAC nomenclature of organic chemistry - Wikipedia

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

    The shorter of the two chains becomes the first part of the name with the -ane suffix changed to -oxy, and the longer alkane chain becomes the suffix of the name of the ether. Thus, CH 3 OCH 3 is methoxymethane, and CH 3 OCH 2 CH 3 is methoxyethane (not ethoxymethane). If the oxygen is not attached to the end of the main alkane chain, then the ...

  6. 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 ...

  7. Functional group - Wikipedia

    en.wikipedia.org/wiki/Functional_group

    In traditional nomenclature, the first carbon atom after the carbon that attaches to the functional group is called the alpha carbon; the second, beta carbon, the third, gamma carbon, etc. If there is another functional group at a carbon, it may be named with the Greek letter, e.g., the gamma-amine in gamma-aminobutyric acid is on the third ...

  9. Cycloalkene - Wikipedia

    en.wikipedia.org/wiki/Cycloalkene

    This is because the bond angle for an alkene, C-C=C, is 122°, while the bond angle for an alkane, C-C-C, is 112°. When these carbons form a small ring, the alkene which has a larger bond angle will have to compress more than the alkane causing more bond angle strain. [4] Cycloalkenes have a lower melting point than cycloalkanes of the same size.
