A) \[C{{H}_{3}}-C{{H}_{2}}-Cl+O{{H}^{-}}\]
B) \[C{{H}_{3}}-\underset{C{{H}_{3}}}{\overset{Cl}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,}}}\,-C{{H}_{3}}+O{{H}^{-}}\]
C) \[C{{H}_{3}}-\overset{Cl}{\mathop{\overset{|}{\mathop{CH}}\,}}\,-C{{H}_{3}}+O{{H}^{-}}\]
D) \[C{{H}_{3}}-C{{H}_{2}}-\underset{C{{H}_{3}}}{\overset{Cl}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,}}}\,-C{{H}_{3}}+O{{H}^{-}}\]
Correct Answer: A
Solution :
\[{{S}_{N}}2\]mechanism means bimolecular nudeophilic substitution mechanism. In this, rate of reaction is determined by concentration of two molecules. It is characteristic of \[1{}^\circ \] alkyl halides. (a) \[\underset{1{}^\circ \,alkyl\,halide}{\mathop{C{{H}_{3}}-C{{H}_{2}}-Cl+O{{H}^{-}}}}\,\] (b)\[\underset{3{}^\circ \,alkyl\,\,halide}{\mathop{C{{H}_{3}}-\underset{C{{H}_{3}}}{\overset{Cl}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,}}}\,-C{{H}_{3}}+OH}}\,\] (c)\[\underset{2{}^\circ \,alkyl\,halide}{\mathop{C{{H}_{3}}-\underset{Cl}{\mathop{\underset{|}{\mathop{CH}}\,}}\,-C{{H}_{3}}+O{{H}^{-}}}}\,\] (d)\[\underset{2{}^\circ \,alkyl\,halide}{\mathop{C{{H}_{3}}-C{{H}_{2}}-\underset{C{{H}_{3}}}{\overset{Cl}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,}}}\,-C{{H}_{3}}+O{{H}^{-}}}}\,\]You need to login to perform this action.
