ORGANIC REACTION, CONVERSIONS, MECHANISMS AND SOLVED PROBLEMS

Organic reactions are chemical reactions involving organic compounds. The basic organic chemistry reaction types are addition reactionselimination reactionssubstitution reactionspericyclic reactionsrearrangement reactionsphotochemical reactions and redox reactions 

Converting one organic compound to another organic compound by using one or more other organic compounds or reagents by a single or multiple steps is called an organic conversion
The mechanism of an organic reaction is the sequence of steps in the reaction, including details of what bonds are formed and/or broken in each step.   Understanding the mechanisms of organic reactions is key to understanding Organic Chemistry, and is also essential to being able to use the reactions to make useful compounds.
