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 −CnH2n+1. A cycloalkyl group is derived from a cycloalkane by removal of a hydrogen atom from a ring and has the general formula −CnH2n−1 ...
If the alkyl group is not attached at the end of the chain, the bond position to the ester group is suffixed before "-yl": CH 3 CH 2 CH(CH 3)OOCCH 2 CH 3 may be called butan-2-yl propanoate or butan-2-yl propionate. [citation needed]. The prefix form is "oxycarbonyl-" with the (R') group preceding.
Quaternary ammonium cation. The R groups may be the same or different alkyl or aryl groups. Also, the R groups may be connected. In organic chemistry, quaternary ammonium cations, also known as quats, are positively-charged polyatomic ions of the structure [NR 4] +, where R is an alkyl group, an aryl group [1] or organyl group.
Category. : Alkyl groups. Alkyl groups are saturated hydrocarbons substituents with the general formula C n H 2n+1 . Wikimedia Commons has media related to Alkyl groups.

The following is a list of straight-chain alkanes, the total number of isomers of each (including branched chains), and their common names, sorted by number of carbon atoms. [1][2] Number of C atoms. Number of isomers [3][4] Number of isomers including stereoisomers [3][5] Molecular Formula. Name of straight chain.
A 3D model of ethyne (acetylene), the simplest alkyne. In organic chemistry, an alkyne is an unsaturated hydrocarbon containing at least one carbon —carbon triple bond. [1] The simplest acyclic alkynes with only one triple bond and no other functional groups form a homologous series with the general chemical formula CnH2n−2.
General structure of an imine. Schiff bases are imines in which R 3 is an alkyl or aryl group (not a hydrogen). R 1 and R 2 may be hydrogens General structure of an azomethine compound. In organic chemistry, a Schiff base (named after Hugo Schiff) is a compound with the general structure R 1 R 2 C=NR 3 (R 3 = alkyl or aryl, but not hydrogen).
For other uses of "ring structure", see Ring structure. A heterocyclic compound or ring structure is a cyclic compound that has atoms of at least two different elements as members of its ring (s). [ 1 ]Heterocyclic organic chemistry is the branch of organic chemistry dealing with the synthesis, properties, and applications of organic heterocycles.
