Question

The nucleophilicity is different from the basicity. Explain.

Answer 1

Basicity is a measure of how readily an atom donates its electron pair to a proton.

It is characterized by an equilibrium constant, Ka in an acid-base reaction, making it a thermodynamic property.

Nucleophilicity is a measure of how readily an atom donates its electron pair to other atoms.

It is characterized by a rate constant, k, making it a kinetic property.
