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 :
\[{{S}_{N}}2\]reaction: \[N{{u}^{o-}}+R-X\xrightarrow{\text{slow}}\underset{\text{Transition}\,\text{state}}{\mathop{Nu-R-X}}\,\] \[\xrightarrow{Fast}Nu-R+{{X}^{-}}\] Order of reactivity: \[C{{H}_{3}}X>{{1}^{o}}>{{2}^{o}}>{{3}^{o}}.\] Hence, the correct option is [c].You need to login to perform this action.
