a) In this mechanism, rate determining step involve both alkyl halide and base. Thus, rate = K[Alkyl halide][base]
This rate law is same as that of E2 reaction.
b) In E2 mechanism, a transition state is formed and in E1cb, carbanion intermediate is formed. This is the difference in two mechanism.
5. There is another mechanism that was proposed as an alternative to the E2 mechanism- it...

5. Molecules with an-OH group directly bonded to a C-C sp hybridized carbon are called "enol"'s. The types of chemical reactions which enols undergo are substantially different from those of normal alcohols. By considering the Brensted-Lowry and Lewis acid/base reactivity of an enol, you can predict a few of these differences. (a) Ethenol, the simplest "enol", can react as a BL. base in three different places, by gaining a proton at either of the two...
A. Introduction and Objective Every test has at least two sources of variation that affect the results of the test. The first source of variation is due to the experimental procedure, such as using two different testing machines that have different calibrations, or different observers reading the same equipment differently. This type of variation is often called the experimental error The second source of variation is inherent in the specimens (or sample population) themselves. In other words, no two specimens...
Partner: Date Name 11 Snell's Law Introduction When light passes from one material to another it is always bent away from its original path. This process is known as refraction and the change in direction depends on the change in optical density (or refractive index) of the two materials. A larger change in refractive index results in a larger change in angle between incoming and outgoing light beams. A light beam bends closer to the normal in the material with...
In Java plz due today Assignment 4 - Email, Shwitter and Inheritance Select one option from below. All (both) options are worth the same number of points. The more advanced option(s) are provided for students who find the basic one too easy and want more of a challenge. OPTION A (Basic): Message, EMail and Tweet Understand the Classes and Problem Every message contains some content ("The British are coming! The British are coming!"). We could enhance this by adding other...
Explain the discovery, mechanism of action and function of AID
(activation-induced deaminase)?
SOMATIC HYPERMUTATION (Figures 7 and 8). Indeed, the discovery of AID provided the missing MSH2-deficient mice had previously been taken to indicate that somatic mutation is initiated by diversification at C:G pairs with MSH2-mediated recognition then triggering a subsequent stage of diversification at A:T pairs. Such a two-stage model was supportedations by the observation that CG-biased mutation was also a characteristic of somatic mutation in B-c nes9 and...

Please help!!!
The Chemistry of Cocaine by Brahmadeo Dewprashad Department of Science Borough of Manhattan Community College, The City University of New York Professor Martinez entered the classroom with a livelier step than usual. Her morning students were accustomed to their instructor's ritual of carefully unpacking her book bag and arranging the contents neatly on the desk before beginning a lecture. But this time Martinez simply set her bag down on the chair, turned to the class, and began. "Today,...
Question 2: Agenda Setting Consider there are three groups of people in Congress: Liberals, Moderates, and Conservatives. It does not matter the size of the groups - just that none of the groups is large enough for a majority - so it requires two groups to vote a certain way for something to pass. Therefore we can treat this like three people and voting where majority rules (another example of this is you with two friends trying to decide on...
Physics Lab Assignment This particular discovery is also an example of how those who deserve an award sadly are not always the ones who receive it. Read the following passage focusing your attention on the scientific procedures and scientific abilities you have been developing throughout the course. The discovery of pulsars –rotating neutron stars that generate regular pulses of radiation at their spin rate- was fortuitous. A group of astrophysicists from Cambridge University lead by Anthony Hewish was looking for...
