sn reactions

The nucleophilic substitution reactions can be classified into two types: First is the S N 1 reaction (substitution nucleophilic, first order). This type of reaction proceeds in two steps as: The first step is slow and is the rate-determining step. As the nucleo..

It is extensively used in organic and inorganic reactions as a versatile reducing agent. It is used to prepare hydrides of elements like B, Al, Sn, etc..
