alkyl group (ăl`kĭl), in chemistry, group of carbon and hydrogen atoms derived from an alkane alkane (ăl`kān), any of a group of aliphatic hydrocarbons whose molecules contain only single bonds (see chemical bond ). .....

Click the link for more information. ). The name of the alkyl group is derived from the name of its alkane by replacing the -ane suffix with -yl, e.g., methyl, CH3, from methane, CH4, and ethyl, C2H5, from ethane, C2H6. In some cases different alkyl groups can be formed from the same alkane by removing different hydrogen atoms; the alkyl groups are then distinguished by adding a prefix, e.g., 1-propyl or n-propyl, CH2CH2CH3, and 2-propyl or isopropyl, CH(CH3)2, both formed from propane, CH3CH2CH3. When a functional group functional group, in organic chemistry, group of atoms within a molecule that is responsible for certain properties of the molecule and reactions in which it takes part. .....

| Alkyl aniline promoters for polyester resins promote ambient and
low temperature decomposition of peroxide catalysts, allowing for better
control of resin curing and gell times. The strong odor so typical of these herbs is caused by a variety of
sulfur compounds such as alkyl sulfoxides and allyl sulfides. Finally, the development of silane types can also receive an
arbitrary classification: Past = alkyl and organoreactive trimethoxy
types; present = trimethoxy, triethoxy; and future = mixtures,
hydrolyzates and bis-silanes. |
