Risk Evaluation for 1-Bromopropane (1-BP) US EPA
WebAcetate, for example, is a weak base but a reasonably good nucleophile, and will react with 2-bromopropane mainly as a nucleophile. In order to direct the reaction towards elimination rather than substitution, heat is often used. This is because elimination leads to an increase in the number of molecules (from two to three in the above example ... WebJul 31, 2024 · The reaction of 2-bromopropane with sodium ethoxide in ethanol provides a good example: Elimination to give propene competes with substitution to give ethyl isopropyl ether. Furthermore, the rate of elimination, like the rate of substitution, is proportional to the concentrations of 2-bromopropane and ethoxide ion. Thus elimination here is a ... astro kerala
