"WebReactivity order : (CH 3) 3 C- > (CH 3) 2 CH- > CH 3 CH 2 - > CH 3 - In an E1 reaction, the rate determining step is the loss of the leaving group to form the intermediate carbocation. The more stable the carbocation is, the easier it is to form, and the faster the E1 reaction will be. " - E2 reactivity order

WebThe rate of the E2 reaction increases as the strength of the base increases. In general, heavy negatively charged bases such as OH are used out in E2 reaction. The rate of E2 reactions is increased by Polar aprotic solvents. The stronger the leaving group, the quicker the E2 reaction. The reaction rate follows the order, R-I > R-Br > R-Cl > R-F. WebE2 is a bimolecular second-order reaction. Both E1 and E2 reactions yield alkene as the product. The factors that favor E1 reaction are the same factors that favor SN1 reaction. A polar aprotic solvent favors the E2 reaction; In the case of E1 reactionThe solvent can be protic or Aprotic but it must be polar as polar solvent favors E1 reaction.

Here, in contrast to the E2 reaction mechanism, we delve into the aspects of the E1 reaction mechanism, which has two steps: rate-limiting loss of the leaving group and abstraction of the beta hydrogen by a weak base. Typically, the experimental proof for the E1 mechanism is via kinetic studies or ...
