Compound A, an alkyl bromide with chemical formula , reacts with to yield compound B. Compound B in turn reacts with (1) , (2) ,
leonid [27]

Compound B will be propene as a result of an elimination reaction involving potassium tert-butoxide and an alkyl halide. In proton NMR, alkenes exhibit signals in the 5–6 ppm range.

<h3>What are Elimination Reactions?</h3>

Elimination reactions are one sort of reaction that are mostly utilized to convert saturated compounds (organic molecules that contain single carbon-carbon bonds) to unsaturated compounds (compounds that feature double or triple carbon-carbon bonds). Additionally, it plays a significant role in the production of alkenes.

The elimination response is composed of the following three major events: 

  1. Proton exclusion.  
  2. The synthesis of a C-C pi bond. 
  3. As a result, the relationship between the departing group's members has grown increasingly distant.
