A) \[{{1}^{o}}>{{2}^{o}}>{{3}^{o}}>C{{H}_{3}}X\]
B) \[C{{H}_{3}}X>{{3}^{o}}>{{2}^{o}}>{{1}^{o}}\]
C) \[C{{H}_{3}}X>{{1}^{o}}>{{2}^{o}}>{{3}^{o}}\]
D) \[{{3}^{o}}>{{2}^{o}}>{{1}^{o}}>C{{H}_{3}}X\]
Correct Answer: C
Solution :
Since, \[{{S}_{N}}2\] pathway involves back side attack, less hindered alkyl halides are more reactive towards this process. As the number of bulkier group increases, hindrance increases, thus \[{{1}^{o}}\]alkyl halides are most reactive and \[{{3}^{o}}\]alkyl halides are least reactive towards \[{{S}_{N}}2\] reactions. Hence, the order of rate of hydrolysis of given halides by \[{{S}_{N}}2\]pathway is \[C{{H}_{3}}X>{{1}^{o}}>{{2}^{o}}>{{3}^{o}}\]
