Nucleophilicity & Basicity r relaled but r diff terms Basicity is the affinity for a proton but Nucleophilicity is the ability to form bonds with C atoms it must be kept in mind that Basicity is thermodynamically controlled where as nucleophilicity is kinetically controlled for e.g iodide ion is weakest base amomg halides but it is best nucleophile due to solvation effect Similarly in the case given C₂H₅O^-1 is a better nucleophile although it is a weaker base than (CH₃)₂CHO^-1later even being a stronger base is a weaker nucleophile bec its large bulk hinders it from closely approaching the substrate.
