WebSummary. A reaction mechanism is the sequence of elementary steps by which a chemical reaction occurs. A reaction that occurs in two or more elementary steps is called a multistep or complex reaction. A reaction intermediate is a chemical species that is formed in one elementary step and consumed in a subsequent step. WebAs we know that the carbocations are very reactive due to their electron deficiency, vacant orbital and incomplete octet. Therefore, its stability depends on the octet completion and reducing the electron deficiency. The stability of a carbocation can be achieved by the following processes: (a) Addition of a nucleophile. (b) Formation of a pi bond.
