  2. Alkyl group - Wikipedia

    en.wikipedia.org/wiki/Alkyl_group

    The numbers are included in the name to avoid ambiguity about the position of the groups, and "tri" indicates that there are three identical methyl groups. If one of the methyl groups attached to the third carbon atom were instead an ethyl group, then the name would be 3-ethyl-2,3-dimethylpentane.

  3. List of esters - Wikipedia

    en.wikipedia.org/wiki/List_of_esters

    An ester of carboxylic acid.R stands for any group (organic or inorganic) and R′ stands for organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (−R).

  4. Ester - Wikipedia

    en.wikipedia.org/wiki/Ester

    Methyl and ethyl esters are commonly available for many amino acids; the t-butyl ester tends to be more expensive. However, t -butyl esters are particularly useful because, under strongly acidic conditions, the t -butyl esters undergo elimination to give the carboxylic acid and isobutylene , simplifying work-up.

    It also maintains List I of chemicals and List II of chemicals, which contain chemicals that are used to manufacture the controlled substances/illicit drugs. The list is designated within the Controlled Substances Act [ 1 ] but can be modified by the U.S. Attorney General as illegal manufacturing practices change.

  8. Ethyl group - Wikipedia

    en.wikipedia.org/wiki/Ethyl_group

    Ethyl group (highlighted blue) as part of a molecule, as the ethyl radical, and in the compounds ethanol, bromoethane, ethyl acetate, and ethyl methyl ether.. In organic chemistry, an ethyl group (abbr. Et) is an alkyl substituent with the formula −CH 2 CH 3, derived from ethane (C 2 H 6).

  9. Methyl group - Wikipedia

    en.wikipedia.org/wiki/Methyl_group

    [15] [16] The term "methyl" was derived in about 1840 by back-formation from "methylene", and was then applied to describe "methyl alcohol" (which since 1892 is called "methanol"). Methyl is the IUPAC nomenclature of organic chemistry term for an alkane (or alkyl) molecule, using the prefix "meth-" to indicate the presence of a single carbon.
