Question

Which of the following organic chloro compound shows stereochemical inversion during a $S_{N}2$ reaction?

• A. $(C{H}_3{)}_{3}CCl$
• B. $(C{H}_3{)}_{2}CHCl$
• C. $(C_2{H}_5{)}_{2}CHCl$
• D. $C{H}_{3}Cl$

Answer 1

Answer: (D)

$C{H}_{3}Cl$

Since, we know that primary halides show inversion during $S_{N}2$ reaction more than secondary while secondary show mare than tertiary. Therefore, $C{H}_{3}Cl(1^o$ halide) show stereochemical inversion more in comparision to $\left(C{H}_3{)}_{3}CCl\right(3^o$ halide), $\left(C{H}_3{)}_{2}CHCl\right(2^o$ halide) and $\left(C_2{H}_5{)}_{2}CHCl\right(2^o$ halide).
