The effect of different solvents on the intermolecular interactions between benzene and toluene molecules can be understood by considering the polarity and solvation properties of the solvents. Intermolecular interactions between benzene and toluene molecules primarily involve van der Waals forces, specifically London dispersion forces, and - stacking interactions.1. Nonpolar solvents: In nonpolar solvents like hexane or carbon tetrachloride, the intermolecular interactions between benzene and toluene molecules will be relatively unaffected. This is because the solvent molecules do not have significant dipole moments and do not interact strongly with the aromatic molecules. As a result, the benzene and toluene molecules will still be able to interact with each other through van der Waals forces and - stacking interactions.2. Polar solvents: In polar solvents like water or methanol, the intermolecular interactions between benzene and toluene molecules can be weakened. This is because the polar solvent molecules can form strong dipole-dipole interactions and hydrogen bonds with each other, which can disrupt the van der Waals forces and - stacking interactions between the aromatic molecules. In some cases, the polar solvent molecules can also form solvation shells around the benzene and toluene molecules, further reducing their ability to interact with each other.3. Polar aprotic solvents: In polar aprotic solvents like acetone or dimethyl sulfoxide DMSO , the intermolecular interactions between benzene and toluene molecules can be moderately affected. These solvents have significant dipole moments but cannot form hydrogen bonds with the aromatic molecules. As a result, they can still solvate the benzene and toluene molecules and disrupt their intermolecular interactions to some extent, but not as effectively as polar protic solvents.4. Solvents with aromatic character: In solvents with aromatic character like chlorobenzene or anisole, the intermolecular interactions between benzene and toluene molecules can be enhanced. This is because the solvent molecules can also participate in - stacking interactions with the aromatic molecules, which can lead to the formation of larger supramolecular structures.In summary, the effect of different solvents on the intermolecular interactions between benzene and toluene molecules depends on the polarity, solvation properties, and aromatic character of the solvents. Nonpolar solvents have little effect on the interactions, while polar solvents can weaken them. Polar aprotic solvents have a moderate effect, and solvents with aromatic character can enhance the interactions.
