Text of the page (random words):
groups 11 involved formation of new carbon carbon bond and 10 involved functional group interconversions by mechanism edit there is no limit to the number of possible organic reactions and mechanisms 5 6 however certain general patterns are observed that can be used to describe many common or useful reactions each reaction has a stepwise reaction mechanism that explains how it happens although this detailed description of steps is not always clear from a list of reactants alone organic reactions can be organized into several basic types some reactions fit into more than one category for example some substitution reactions follow an addition elimination pathway this overview isn t intended to include every single organic reaction rather it is intended to cover the basic reactions reaction type subtype comment addition reactions electrophilic addition include such reactions as halogenation hydrohalogenation and hydration nucleophilic addition radical addition elimination reaction include processes such as dehydration and are found to follow an e1 e2 or e1cb reaction mechanism substitution reactions nucleophilic aliphatic substitution with s n 1 s n 2 and s n i reaction mechanisms nucleophilic aromatic substitution nucleophilic acyl substitution electrophilic substitution electrophilic aromatic substitution radical substitution organic redox reactions are redox reactions specific to organic compounds and are very common rearrangement reactions 1 2 rearrangements pericyclic reactions metathesis in condensation reactions a small molecule usually water is split off when two reactants combine in a chemical reaction the opposite reaction when water is consumed in a reaction is called hydrolysis many polymerization reactions are derived from organic reactions they are divided into addition polymerizations and step growth polymerizations in general the stepwise progression of reaction mechanisms can be represented using arrow pushing techniques in which curved arrows are used to track the movement of electrons as starting materials transition to intermediates and products by functional groups edit organic reactions can be categorized based on the type of functional group involved in the reaction as a reactant and the functional group that is formed as a result of this reaction for example in the fries rearrangement the reactant is an ester and the reaction product an alcohol an overview of functional groups with their preparation and reactivity is presented below functional group preparation reactions acid anhydride preparation

preparation reactions ketones preparation reactions lactams preparation reactions lactones preparation reactions nitriles preparation reactions nitro compounds preparation reactions phenols preparation reactions thiols preparation reactions other classification edit in heterocyclic chemistry organic reactions are classified by the type of heterocycle formed with respect to ring size and type of heteroatom see for instance the chemistry of indoles reactions are also categorized by the change in the carbon framework examples are ring expansion and ring contraction homologation reactions polymerization reactions insertion reactions ring opening reactions and ring closing reactions organic reactions can also be classified by the type of bond to carbon with respect to the element involved more reactions are found in organosilicon chemistry organosulfur chemistry organophosphorus chemistry and organofluorine chemistry with the introduction of carbon metal bonds the field crosses over to organometallic chemistry see also edit list of organic reactions other chemical reactions inorganic reactions metabolism organometallic reactions polymerization reactions
