Sn [F3) Any compound or ion with at least one lone pair can be considered a base and/or a nucleophile. The relative basicity and nucleophilicity of the species is one of the most important factors that determine the mechanism of a reaction on sp³-carbon atoms. Please show an example of a) a reagent that is a strong nucleophile and a strong base, b) a reagent that is a weak nucleophile and a strong base, c) a reagent that is a strong nucleophile and a weak base, d) a reagent that is a weak nucleophile and a weak base.
