10.17 Out of C6H5CH2Cl and C6H5CHClC6H5, which is more easily hydrolysed by aqueous KOH. NEETprep Audio Note (English):    


            

Hydrolysis by aqueous KOH proceeds through the formation of carbocation. If carbocation
is stable, then the compound is easily hydrolyzed by aqueous KOH. Now, C6H5CH2Cl      
forms 1°-carbocation, while forms    C6H5CHCLC6H5    2°-carbocation, which
is more stable than 1°-carbocation. Hence,   C6H5CHClC6H5 is hydrolyzed more easily
than C6H5CH2Cl      by aqueous KOH.
