Mechanism of ethene to ethanol
WebDec 3, 2024 · Given above is the mechanism that I drew but my textbook puts it a bit differently. It says that the ethene is dissovled in the concentrated $\ce{H2SO4}$ to form ethyl hydrogen sulphate $\ce{CH3-CH2OSO3H}$ which when diluted with water reacts to form ethanol and the acid $$\ce{CH3CH2OSO3H + H-OH -> CH3CH2OH + H2SO4}$$ So … WebThe πpart of the bond breaks and the electrons in it move down to make a new bond with the hydrogen atom. That forces the electrons in the hydrogen-oxygen bond down entirely onto the oxygen. Note: It is easy to see why the oxygen carries a negative charge. It has gained full control over the electron pair in the original bond – so has ...
