Question

why does C60 dissolve in benzene, whereas diamond doesnt

Answer 1

All three are non polar covalent so that's not the reason. Diamond is a lattice polymer of carbon each molecule MW probably in the millions, very small surface to volume ratio it simply cannot solvate. It is similar to crosslinked and thermoset plastics or lattice minerals like quartz. Graphite is a bit different being composed of graphene sheets bonded by van der Waals forces. The problem here seems to be molecular weight because the surface to mass ratio is high. Graphite shows limited solubility under duress and a lot of work is ongoing to solubilize graphene. C60 fullerene is not MW restricted altho its surface area ratio is small. It shows limited [mg/mL] solubility in many organic solvents. Many noncrosslinked linear polymers are soluble in a number of organic solvent even to quite high molecular weights. This property is used in gel permeation chromatography to measure molecular weight distributions.

Answer 2

hey dear here is ur answer _______

☆ diamond does not dissolve Becoz diamond is too big to be solved and its bonds is too strong .
