    Distinguish between S_(N^(1))andS_(N^(2)) mechanism.

    The polarity of the carbon-halogen bond is responsible for the nucleophilic substitution reactions of alkyl halides which mostly occur by S_(N)1 and S_(N)2 mechanisms. The rates of S_(N)2 reactions among other things are governed by steric factors while than of S_(N)1 reactions are governed by the stability of intermediate carbocations. chirality has a profound role in undersetanding the mechanism of S_(N)1 and S_(N)2 reactions. whereas S_(N)2 reactions of chiral alkyl halides are accompanied by inversion of configuration, S_(N)1 reactions are characterised by racemisation. Q. S_(N)1 reaction of optically active alkyl halides leads to
