In the reaction the given below The incorrect statement concerning the above reation is are .

Answer»

(I) is the major elimination product
(II) is formed at faster rate than (I)
(I) is formed at faster rate than (II)
increasing order of reactivity with different `X` is `FltCIltBrltI` .

Solution :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 stabilityof 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 .
