In electrophilic aromatic substitution, the benzene ring acts as an electron donor (Lewis base or nucleophile) and reacts with an electron acceptor (Lewis acid or electrophile). The result of electrophilic aromatic substitution reactions is that an aromatic hydrogen is replaced by some other atom or functional group.
Specifically, the MD simulations of S&vdV confirm that: (a) the benzeneâwater van der Waals interaction energy overwhelms in magnitude the work of cavity creation; (b) the enthalpic contribution of the weak benzeneâwater H-bonds is to a large extent compensated for by a corresponding entropic contribution.n order to address the role played by the weak benzeneâwater H-bonds, S&vdV studied a real benzene model that favors the formation of such weak H-bonds as well as a van der Waals, vdW, benzene model obtained by removing all partial charges of the first model and keeping the dispersion interactions unaffected.
