(For the non-chemists in the audience, the problem here is that sodium hydride is most certainly not what you'd think of as an oxidizing reagent, quite the opposite, in fact. Seeing the paper's title was, for an organic chemist, a bit like reading ...

WitrynaYes. Sn1 reactions depend on the stability of the cation formed when the Leaving group had left. So, since tertiary carbocations are most stable of the three will undergo Sn1 reaction easily. Sn2 reactions depend on the fastness of the leaving group. The fastness depends on the Leaving group. WitrynaAlcohol Reactions. The functional group of the alcohols is the hydroxyl group, –OH. Unlike the alkyl halides, this group has two reactive covalent bonds, the C–O bond and the O–H bond. The electronegativity of oxygen is substantially greater than that of carbon and hydrogen. Consequently, the covalent bonds of this functional group are ...

WitrynaSome alcohols are much more acidic; for example –OH groups attached to an aromatic ring (which are called phenols) typically have pK a ‘s around 10. This difference in pK a must lie with the nature of the conjugate base (the anion), since the same O–H bond breaks during the proton transfer. In this case, the conjugate base is stabilized by … WitrynaOne of the products on the right side is the protonated form (conjugate acid) of the alkoxide which is an alcohol. The product in this reaction is a 3 o (tertiary) alcohol which are less acidic and are at the higher end of the alcohol pKa range (16-18). An appropriate reagent for the protonation would be one with a pKa lower than 18.
