In organic chemistry, an addition reaction is an organic reaction in which two or more molecules interact to generate a bigger one (the adduct). Because the reaction causes the carbon atoms to become saturated with the greatest amount of linked groups. Addition reactions to alkenes and alkynes call to as saturation reactions.
The hydrochlorination of propene (an alkene), for which the formula is, is an example of a typical addition reaction.
The order of events overturns in reactions to aldehydes and ketones. The element of the reagent with a negative charge adds to the carbon atom first. The element of the reagent with a negative charge adds to the oxygen atom.
Electron-seeking (electrophilic) reagents are said to commence the hydrochlorination of propene and, in general, the addition to alkenes, whereas electron-rich reagents are thought to initiate the addition to alkynes, aldehydes, and ketones.
Other types of addition reactions include catalyzed addition processes, such as the self-addition of alkenes (catalyzed by acids) or the hydrogenation of alkenes, aldehydes, and ketones (catalyzed by metals); cyclic compound formation; and chain mechanism addition reactions.
Chemical compounds hold numerous bonds, such as molecules with carbon-carbon double bonds (alkenes) or triple bonds (alkynes), and compounds with rings, which are also termed points of unsaturation. Chemical compounds remove from addition processes. Molecules with carbon—hetero double bonds, like carbonyl (C=O) or imine (C=N) groups, joined because they have double-bond character as well.
An elimination reaction is the polar opposite of an addition reaction. Dehydration is a chemical process that reverses the hydration of an alkene to alcohol.
Electrophilic and nucleophilic addition are the two basic forms of polar addition processes. Free-radical addition and cycloadditions are 2 non-polar addition processes that take place. Polymerizations can also involve additional processes, call addition polymerization.
