phymatter said:I have read that basicity is compared by equlibrium and nucleophilicity by kinetics , then how do we compare basicity with nucleophilicity ??
That is if there is a negatively charged molecule and H+ and a carbocation , how do we come to know which will be attacked by the negatively charged molecule ?
One thing to think about is that equilibrium is the point where the forward reaction rate is equal to the reverse reaction rate. With equilibrium you are concerned about the energy difference between reactants and products, but in a kinetics problem you're more concerned with the energy difference between the reactants and the activated state.

Nucleophilicity refers to the ability of a chemical species to donate a pair of electrons to form a new chemical bond. Basicity, on the other hand, refers to the ability of a species to accept a proton. While both concepts involve the donation or acceptance of electrons, the key difference is that nucleophilicity involves the formation of a new bond, while basicity involves the formation of a new acid-base pair.
Nucleophilicity and basicity are related in that both concepts involve the donation or acceptance of electrons. However, the factors that affect nucleophilicity and basicity may differ. For example, a highly polarizable species may be a strong nucleophile but a weak base, while a highly electronegative species may be a weak nucleophile but a strong base.
The factors that affect nucleophilicity include the charge and size of the nucleophile, as well as the solvent and the presence of other functional groups in the molecule. In general, larger and more negatively charged species tend to be stronger nucleophiles.
Basicity can greatly affect a molecule's reactivity. A high basicity can make a molecule more reactive towards acids, while a low basicity can make a molecule less reactive. Basicity can also affect the stability of a molecule, as highly basic molecules tend to be less stable and more reactive.
The ability of a molecule to act as a nucleophile is inversely related to its ability to function as a leaving group. This means that a strong nucleophile is usually a poor leaving group, and vice versa. This is due to the different electronic requirements for these two roles in a reaction - a strong nucleophile needs a high electron density to donate, while a good leaving group needs a low electron density to accept.
