In those reactions, the use of polar protic solvents favors the S N1 … Witryna2 sty 2024 · Explanation: In water, it is well known that the strongest base that can exist is −OH anion. Bases that are nominally stronger than hydroxide, for instance amide ion, would undergo reaction with the solvent: −N H 2 +H 2O(aq) → N H 3(aq) +H O− c with slash through it symbolWitryna16 sie 2024 · Yes, Ch3OH (methanol) can not only act but it is a nucleophile mostly a weak one. Considering the structure of the CH3OH molecule, there is a presence of O-H bond and we can say that it is technically protic where it can readily donate hydrogen ions. Additionally, this characteristic also makes the molecule polar. cheap gifts for bus drivers
