WebA: antiperiplanar, anti or trans. B: synclinal or gauche. C: anticlinal or eclipsed. D: synperiplanar or cis. [4] There are both steric and electronic effects that affect the relative stability of conformers. Ordinarily, steric effects predominate to place large substituents far from each other. WebThe heat of combustion of cis-1,2-dimethylcyclopropane is larger than that of the trans isomer. Which isomer is more stable? Use drawings to explain this difference in stability WebIn addition, trans–alkenes are generally more stable than cis-alkenes, so we can predict that more of the trans product will form compared to the cis product. However, certain other eliminations (which we will not be studying) favor the least substituted alkene as the predominant product, due to steric factors. Such a product is known as the ... note taking color coding
