Organic reaction

I. What are organic reactions?
Organic reactions are chemical reactions involving organic compounds.

II. How many main types of organic reaction are there?
Base change of organic compound molecules, there are 5 main types. These are addition reaction, substitution reaction, elimination reaction, decompose reaction, isomeric reaction, condensed reaction.

1. Addition reaction is an organic reaction where two or more molecules combine together to form a new molecule.
Including:
+ Electrophilic addition (AE), AE is a addition reaction which attack agent belong electrophiles.
+ Nucleophilic addition (AN), reagent are nucleophiles.
+ Radical addition (AR) is a addition reaction involving free radicals.

2. Substitution reaction is a reaction where an atom or group atoms in organic molecule is replaced by another atom or group.
Including:
+ Electrophilic substitution (SE) reactions involve electrophilics.
+ Nucleophilic substitution (SN) happens when the reagent is a nucleophile.
+ Radical substitution (SR) is a substitution reaction that radical is reagent.

3. Elimination reaction is a type of organic reaction in which two atoms or group atoms are removed from a molecule but not have anything substitute.

4. Decompose reaction is reaction in which one molecule is divided into two or more molecules.

5. Isomeric reaction is reaction where happens change place of bonds or group atoms in molecule but molecular formula do not change.
