Elimination reaction is defined as a chemical reaction which involves the elimination of a leaving group to form unsaturated compounds. Know more about the mechanism and examples of elimination reaction here.
The two main types of elimination reactions are E1 and E2.2. E1 Mechanism: - The E1 mechanism is a two-step process where the rate-determining step involves the formation of a carbocation. The stability of the carbocation is crucial for the reaction to proceed....

Exactly! If there was a really good leaving group (like OTs or Br) present instead of OH, an E2 (or even E1) mechanism would be more likely. [Note 2] The bad leaving group (HO-) makes the elimination step is slow, which is largely responsible for this being a two-step mechanism....
Comparing E1 vs E2 Reactions The E1 and E2 reactions may have the same reactant and same product, and they appear to follow the same mechanism. However… The ‘1’ type reaction (E1) is a slow reaction with a carbocation intermediate. This is due to reacting in the presence of a weak...

There is a catch however: the E1 pathway (formation of a primary carbocation) is not the most likely pathway here.Primary carbocations tend to be extremely unstable, and it’s more likely that the reaction passes through an E2 mechanism where the transition state will be lower in energy. No...

The aims of the study were to further understand schistosome development, the nature of the schisto- some development and failure mechanism in M. fortis, and to identify differentially expressed genes that might play a role in the developmental biology and survival of S. japonicu...
However, in the past years our knowledge of biological redox processes has expanded greatly and it is now evident that controlled oxidant generation is not only an important mechanism for environmental adaptation but also that it has essential roles in many aspects of cellular com- munication51. ...
