Similar JEE Doubts

Both the Cβ–H and Cα–X bonds are breaking in the transition state of E2 reactions. The rate of E2 reaction is of second order. The rate shows primary isotopic (deuterium) effect, i.e. if Cβ–H is replaced by Cβ–D, the rate of reaction decreases sharply. The rate is also corelated with nucleofugality i.e. the ability of leaving group to leave. With a better nucleofuge, the rate of reaction increases. This is called the element effect.The element effect is also observed in E1cB reactions in which the second step is rate determining and elimination of first order w.r.t. conjugate base is observed. For E1cB reaction KH/KD ~ 1, therefore proton abstraction is not involved in the rate determing step. In D2O the incorporation of Deuterium at Cβ–H in the substrate is found many times faster than rate of elimination, in E1cB reaction.In E1 reaction only nucleofuge departs in slow step and a carbocation intermediate is formed.Q.Consider the following statement, “In 80% aqueous ethanol, t-Butyl iodide solvolyses 100 times as rapidly as t-Butylchloride, but the ratio of elimination to substitution products is the same for chloride and iodide.” This statement indicates that
