Alkylhalides have polar C-X bond and undergo nucleophilic substitution reactions. These give a variety of products with nucleophiles such as -OH, -OR, -NH_(2), -CN, -NC, -NO_(2), -ONO, RCOO^(-), etc. They undergo mainly two types of nucleophilic substitution reactions, S_(N)1 and S_(N)2. S_(N)1 reactions are two steps reactions which proceed through the formation of carbocations while S_(N)2 reactions are one step reaction which proceeds through the formation of transition state. The stability of carbocation and transition state determine the reactivity of alkyl halides. Write the main products A and B in the following reaction. A overset(KNO_(2))larr CH_(3)CH_(2)Br overset(AgNO_(2))to B.
