Question

In the reaction the given below
The incorrect statement concerning the above reation is are
.
A. (I) is the major elimination product
B. (II) is formed at faster rate than (I)
C. (I) is formed at faster rate than (II)
D. increasing order of reactivity with different `X` is `FltCIltBrltI` .

Answer 1

Correct Answer - C
With ethoxide base most substituted alkene (I) is formed as the major product in the formation of (II) `C_(2)H_(5)O` takes proton from less hindered Beta -carbon hence less activation energy and greater rate of reaction althought stability of product determines it content at equilibrium Also since `E2` reaction is an elementary reaction in which halogen leaves in the rate determining step iodide leaves most easily and fluoride with maximum difficulty .
