One might argue how an OH group can be … WebApr 5, 2024 · The pKa value of CH3OH is more than 15. This is a constant that measures the amount of acidic or basic ions in a solution. The weak acidity of methanol is due to the presence of the CH3 functional group. The presence of the OH group can cause it to release OH negative ions in a solution of water. This gives it the properties of a base. the calm classroom instagramWebA few reasons: 1. The C-Br bond is relatively weak (<300kJ/mol) compared to other C-X bonds. The C-I bond is even weaker.

WebJan 23, 2024 · Think about why this might be true. In order for a leaving group to leave, it must be able to accept electrons. A strong bases wants to donate electrons; therefore, the leaving group must be a weak base. We will now revisit electronegativity, size, and resonance, moving our focus to the leaving group, as well providing actual examples. WebDec 22, 2024 · 3 user55119's answer has the details, but the underlying point is that it's empirical.

WebMy book says CH3OH has a lower pka, so it is more acidic. Therefore, CH3O- is a weaker base, and therefore a weaker nucleophile (no sterics here and we're not talking about any solvents so they should correlate). All the logic you gives makes sense to me, but it runs counter to the experimental pka values listed in Vollhardt. WebWe call it a base because if the given compound is deprotonated then it is a proton donor and by Brønsted–Lowry definition the proton donor is the acid in an acid-base reaction. So, we can visualize the task as such, we need something (a base) to react with the phenol and remove the red H: And how do we find this base?
