A) \[{{E}_{2}}\] intra molecular reaction
B) \[{{E}_{1}}\] intra molecular reaction
C) \[{{S}_{N}}1\] intra molecular reaction
D) \[{{S}_{N}}2\] intra molecular reaction
E) Both (a) and (b)
Correct Answer: A
Solution :
Cope reaction is \[{{E}_{2}}\] intra-molecular. ? Cope elimination is a syn-elimination and proceeds through a cyclic transition state. ? The negatively charged oxygen of the amine oxide is the base that remove a proton from \[\beta \text{-}\]carbon. ? Because the nucleophiles and leaving group are in same molecule, this is an intra-molecular\[{{E}_{2}}\]reaction and give less substituted alkene as the major product.You need to login to perform this action.
