elimination reaction उदाहरण वाक्य

The final step involves pyrophosphate held in the trinuclear Mg 2 + center acting as a catalytic base in an elimination reaction to form geranyl pyrophosphate.
In presence of a ?-hydrogen, a selenide will give an elimination reaction after oxidation, to leave behind an alkene and a selenenic acid.
Other cases where hydroxide can act as a nucleophilic reagent are amide hydrolysis, the Cannizzaro reaction, nucleophilic aliphatic substitution, nucleophilic aromatic substitution and in elimination reactions.
More generally, Zaitsev's rule predicts that in an elimination reaction, the most substituted product will be the most stable, and therefore the most favored.
When the reaction site is not sterically hindered, a second iodide can recombine to form the geminal di-iodide; otherwise an elimination reaction leads to the vinyliodide.

The aromatic moiety itself does not participate in elimination reaction, but it does increase the rigidity and strength of the resulting material which leads to Kevlar's renowned strength.
An alternative reaction mechanism involving direct nucleophilic displacement on the peroxide link of the amine followed by an elimination reaction is considered unlikely based on the outcome of this model reaction:
It is widely accepted that the Chichibabin reaction mechanism is an addition-elimination reaction that proceeds through an ?-adduct ( Meisenheimer adduct ) intermediate ( the third structure ).
Zaitsev published his rule for elimination reactions just after Markovnikov published the first article in a three-part series in " Comptes Rendus " detailing his rule for addition reactions.
This then condenses with the arginine side chain to yield glucosepane in nucleophilic addition-elimination reactions of the nitrogens of arginine and the electrophilic carbonyls on the ring, eliminating two waters.
