The organic reactions are those chemical reactions involving organic compounds. The basic organic chemistry reaction types are substitution reactions, substitution reactions, addition reaction, pericyclic reactions, rearrangement reactions and redox. The production of many man-made chemicals such as plastics, food additives, drugs, fabrics depend on organic reactions. Factors governing organic reactions are necessarily the same as that of any chemical reaction. Factors specific to organic reactions are those that determine the stability of reactants and products such as  conjugation,   aromaticity and hyperconjugation  and the presence and stability of reactive intermediates such as free radicals, carbocations and carbonanions. . An organic compound may consist of several isomers. Organic reactions can be preceded by selecting the type of organic reagent, many of them are inorganic, required in a specific transformation. The major types are oxidizing agents like osmium tetroxide, reducing agents like lithium aluminium hydride, bases like  lithium di iso propylamide and acids like sulphuric acid.They can undergo a variety of reactions because of their polar nature and the characteristic reactions are 

1. Nucleophilic reaction

2. Elimination reaction

3. Reaction with metals.

The compounds that are generally versatile compounds react both as nucleophiles and electrophiles.Some compounds like ethers are least reactive of the functional groups. The  cleavage of the C-O bond in ethers takes place under drastic conditions with excess of hydrogen halides. 

Aldehydes and ketones owing to the presence of the carbonyl groups give many common reactions. The reactivity of the carbonyl group decreases with increasing size of the alkyl group attached to it due to steric hindrance. 

In aqueous solutions of carboxylic acids the H atom of the COOH group is released as a proton or hy dronium ion. This gives the carboxylic acid their acidic properties. Despite the low H₃O⁺ concentrations in equilibria, carboxylic acids react active with metals liberating hydrogen, neutralize bases forming salts and water, and liberate CO₂ from carbonates and hydrogen carbonates.
