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 ...
When compounds contain more than one functional group, the order of precedence determines which groups are named with prefix or suffix forms. The table below shows common groups in decreasing order of precedence. The highest-precedence group takes the suffix, with all others taking the prefix form.
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 ...
However, some groups, such as the alkyl group, are less electron-withdrawing than hydrogen and are therefore considered as electron-releasing/ electron-donating groups. This is electron-releasing character and is indicated by the +I effect. In short, alkyl groups tend to give electrons, leading to the induction effect.
Traditionally the names of the alkyl groups were written in order of increasing complexity, for example methyl ethyl ketone. 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 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.

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]
