WebThe lower on the periodic table the halogen is, the faster the rate will be. This is because they form better leaving groups. A good leaving group can be though of as the conjugate of a strong acid; in the case of halogens, the lower on the periodic table the halogen is the more acidic it will be, as it has a larger atomic radius to distribute its negative charge. 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? brucebase 1976

"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. " - Is ch3oh a bulky base

WebIntroduction. The Brønsted-Lowry acid-base theory is still used extensively, but it is very restrictive as it focuses primarily on acids and bases acting as proton donors and acceptors. Sometimes conditions arise where the theory doesn’t necessarily fit, such as in solids and gases. In 1923, G.N. Lewis from UC Berkeley proposed an alternate ... WebWith primary alkyl halides, a substituted base such as KO t Bu and heat are often used to minimize competition from S N 2. The H and the leaving group should normally be antiperiplanar (180 o) to one another. Zaitsev’s Rule applies, unless a very hindered base such as KO t Bu is used, so the more substituted alkene is usually major.

Web3 is a strong nucleophile and base, it will force a 2nd-order mechanism. It is not a bulky base, so the 2° alkyl halide will give a mixture of E2 and S N2 products. b.

WebAs a rule of thumb, when a compound is a strong base, it is a strong nucleophile, too: typical examples are the OH¯/H₂O or CH₃O¯/CH₃OH pairs, in which the first terms are strong nucleophiles whereas the second ones are weak. The same reasoning applies to, say, compounds with negatively charged nitrogen atoms.
