Witryna9 sty 2015 · The nucleophile begins to make a coordinate covalent bond. As the electrons in the π bond move closer towards the oxygen, the O atom becomes increasingly negative. The movement goes on until the Nu is firmly attached to the C atom, and the O atom has a full negative charge. Molecular Orbital Explanation Witryna16 lip 2024 · The rate of ester hydrolysis can also be enhanced by increasing the reactivity of a nucleophile. The hydroxide ion should be used instead of water.

"WitrynaA biomolecular nucleophilic substitution (S N 2) reaction is a type of nucleophilic substitution whereby a lone pair of electrons on a nucleophile attacks an electron deficient electrophilic center and bonds to it, resulting in the expulsion of a leaving group. It is possible for the nucleophile to attack the electrophilic center in two ways. " - Naoh nucleophile
