WebEthoxide is a very strong base and will perform an E2 reaction despite the polar, protic solvent. The nucleophile/base and the substrate are more important for determining what reaction will occur than the solvent. Jay even mentions that there will be an SN2 product despite the decreased nucleophilicity of ethoxide. ( 2 votes) Bennie Zhu WebEthylene oxide is a colorless gas at 25 °C (77 °F) and is a mobile liquid at 0 °C (32 °F) – viscosity of liquid ethylene oxide at 0 °C is about 5.5 times lower than that of water. The gas has a characteristic sweet odor of ether, noticeable when its concentration in air exceeds 500 ppm. [26]

WebIn this post, we will talk about the E2 and E1 elimination reactions of substituted cyclohexanes. Let’s start with the E2 mechanism. When the following substituted cyclohexane is treated with sodium ethoxide, an E2 elimination is expected to occur as we have a strong base reacting with a secondary alkyl halide: WebThe effect is even worse if the nucleophile itself is bulky. However, a nucleophile like tert-butoxide ion is also a strong base. Therefore, it will go for a β hydrogen in an E2 attack. All β hydrogens are equally accessible, because they are terminal atoms — they stick out from the carbon chain. WebIf we look at the $\text {p}K_\text {a}$ of ethanol and phenol we have 16 and 9.95 respectively and so the equilibrium above will strongly favour the right hand side. Therefore, the phenoxide ion will dominate as a nucleophile in the mixture, and the major product will be ethyl phenyl ether. Share Improve this answer Follow tradingriot bootcamp download
