Elimination vs substitution ochem
WebFeb 13, 2024 · In order to understand why some combinations of alkyl halides and nucleophiles give a substitution reaction, whereas other combinations give elimination, and still others give no observable reaction, we must investigate systematically the way in which changes in reaction variables perturb the course of the reaction. WebMar 20, 2024 · Substrate Structure (Primary, secondary or tertiary) determines whether elimination or substitution will take place. 2. Less polar solvent (like ethanol) and higher temperature favours elimination. …

The overall mechanism of an addition-elimination reaction is known as an addition-elimination mechanism. 2. Some nucleophilic aromatic substitution reactions occur via a two-step mechanism in which the first step, by definition, is an addition and the second step an elimination.
WebIn regioselectivity, the more substituted product was the major product. Because of more the substitution, more the stability. In stereoselectivity, trans was the major product. Because trans arrangement kept the bulky groups far away. In stereospecificity, E alkene kept the bulky phenol far away and hence more stable.
