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 2n−1. [2] Typically an alkyl is a part of a larger molecule. In structural formulae, the symbol R is used to designate a generic (unspecified) alkyl group. The smallest alkyl group is methyl, with the formula −CH 3 ...
Alkyl groups are saturated hydrocarbons substituents with the general formula C n H 2n+1 Pages in category "Alkyl groups" The following 7 pages are in this category ...
Alkyl compounds are chemical compounds formally derived from alkanes by replacement of one hydrogen atom with other atoms or functional groups. Alkyl compounds contain alkyl groups , C n H 2 n +1 , and have the general formula C n H 2 n +1 X, where X is any chemical element or group.
A polyolefin is a type of polymer with the general formula (CH 2 CHR) n where R is an alkyl group. They are usually derived from a small set of simple olefins . Dominant in a commercial sense are polyethylene and polypropylene. More specialized polyolefins include polyisobutylene and polymethylpentene. They are all colorless or white oils or ...
However, according to the rules of IUPAC nomenclature, the alkyl groups are written alphabetically, for example ethyl methyl ketone. When the two alkyl groups are the same, the prefix "di-" is added before the name of alkyl group. The positions of other groups are indicated by Greek letters, the α-carbon being the atom adjacent to carbonyl group.
In organic chemistry, alkylidene is a general term for divalent functional groups of the form R 2 C=, where each R is an alkane or hydrogen. [1] They can be considered the functional group corresponding to mono- or disubstituted divalent carbenes (known as alkylidenes), [2] or as the result of removing two hydrogen atoms from the same carbon atom in an alkane.
They are formed by adding the suffix "-yl" to the hydrocarbon prefix. For example, a methyl group (CH3) is an alkyl group derived from methane (CH4). Halo prefixes: These prefixes are used to indicate the presence of a halogen atom (F, Cl, Br, or I) in a molecule. Some examples include: fluoro- (F) chloro- (Cl) bromo- (Br) iodo- (I) Suffixes [3]
In organic chemistry, a methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms, having chemical formula CH 3 (whereas normal methane has the formula CH 4). In formulas, the group is often abbreviated as Me. This hydrocarbon group occurs in many organic compounds. It is a very stable group in ...
