A) An alkene prepared by \[{{E}_{2}}\] mechanism
B) An alkene prepared by \[{{E}_{1}}\] mechanism
C) Dehydrohalogenation of \[PhC{{H}_{2}}C{{H}_{2}}Br\] by strong base.
D) Dehydrohalogenation of \[PhC{{D}_{2}}C{{H}_{2}}Br\] by strong base.
Correct Answer: B
Solution :
[b] In \[E2,\] the rate of reaction depends on the breaking of the\[(C-H)\] or \[(C-D)\] bond, hence it shows \[1{}^\circ \] isotope effect.You need to login to perform this action.
