Carbon benzene interaction, attractive

Chloroform shows a significant binding interaction with benzene, but carbon tetrachloride does not. Predict the preferred geometry for the interaction and describe the physical nature of the attraction between the two molecules. 

Besides benzene and naphthalene dimers, various earbon materials have also attracted attentions in the context of r-stacking interactions. The most frequently targeted systems are nanotube and graphene for their electronic, adsorptive, and reactive properties. So far, many DFT studies have been reported especially for single-walled carbon nanotube (SWCNT) and graphene in the fields of both quantum chemistry and solid state physics. 

In this study, an extraction approach to the problem of attractive interactions in Green River (Mahogany Zone) oil shale resulted in the preferential dissolution of both carbonate and silicate minerals. As the results in Table IV indicate, the interfacial organic layer between kerogen and the inorganic mineral matrix was also simultaneously separated. Since the majority of the bitumen was removed in the initial benzene/
