A carbonium ion produced by heterolysis (decomposition of a compound into oppositely charged particles or ions) may lose a proton, thereby effecting a 1,2-elimination reaction: Such eliminations, which generally accompany nucleophilic substitutions, are promoted by electron release to the carbonium ion centre.
Though he was eliminated last week he survived several eliminations with humorous, sometimes spiteful songs that stung.
Like her counterparts in Sri Lanka and Nepal and elsewhere she already suffers from living in a country beset by political instability, and has to bear the additional burden of frequent cyclones and floods.The effect of the quota eliminations may not, however, turn out to be as bad as some fear.
More thoughtful Mexican farmers, such as Eduardo Palau in Sinaloa, would rather see steadily liberalising trade than subsidies.The 2003 tariff eliminations will, in fact, make almost no material difference.
For now, random and sometimes brutal eliminations allow the young leader to demonstrate the power that he is consolidating.
This situation was clarified by successive eliminations.
Popovich kept San Antonio among the league's elite regular-season teams over the following two years, which included leading the Spurs to a franchise-record 67 wins in 2015 16, but San Antonio met with early play-off eliminations during that span.
The pedigree record is useful in making these eliminations.
Furthermore, the so-called conjugate eliminations occur when one or more double bonds are inserted between carbon atoms bearing the substituents that are eliminated; the result of such eliminations is a system of alternating double and single bonds (a conjugated system).
The simplest examples of this class of reactions are the olefin-forming 1,2-eliminations that is, eliminations of substituents from adjacent carbon atoms—but eliminations to give other types of double bonds are equally well known.
Concerted bimolecular eliminations are characterized by second-order kinetics; they occur readily with powerful nucleophiles.
