WebAug 3, 2015 · Yes, a strong nucleophile can be a weak base. In general, good bases are also good nucleophiles. But weak bases can also be good nucleophiles. They fall into three classes. i) Anions of large atoms "I"^-, "S"^(2-), and "RS"^- are good nucleophiles because they are large ions and their electron clouds are quite polarizable. This means … WebJun 2, 2015 · The key factors that determine the nucleophile's strength are charge, electronegativity, steric hindrance, and nature of the solvent. Charge Nucleophilicity increases as the density of negative charge increases. An anion is always a better nucleophile than a neutral molecule, so the conjugate base is always a better …
WebReactions are impacted by various factors that depend on the mechanism of the reaction.Some of the variables for substitution reactions are: • strength of the nucleophile • concentration of the nucleophile • leaving group ability (i.e., is it a “bad” or a “good” leaving group?In an SN2 reaction, the nucleophile forces the leaving group to leave.
