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. In the solvolysis of 3-methyl-3-bromohexane, which of the followin statements is not correct?

Answer» it involves CARBOCATION INTERMEDIATE the intermediate invovles `sp^(2)` carbon polar solvents accelerate the reaction it involves INVERSION of configuration Solution :Solvolysis means reaction with the solvent. Here, solvent ACTS as the nucleophile. 3-Methyl-3-bromohexane is a `3^(@)` alkyl halide, therefore, it undergoes solvolysis by `S_(N)1` mechanism to afford a racemic product in which both RETENTION and inversion have occurred and not only inversion.
