(a)Graphite, diamond and fullerene are all allotropes of carbon.Graphite Diamond Fullerene(i) Explain, in terms of its structure and bonding, why graphite[3](m.p.= 4200 C) has a lower melting point as compared to diamond(m.p.= 4500 C).(ii) Does fullerene conduct electricity?[2]Expla...
Hint: We know that physical as well as chemical properties are the result from the characteristic structure of a given compound which is why even compounds made from the same element can have different properties.Complete answer:Graphite and diamond are two quite known all...

Superionics are fascinating materials displaying both solid- and liquid-like characteristics: as solids, they respond elastically to shear stress; as liquids, they display fast-ion diffusion at normal conditions. In addition to such scientific interest,
Diamond is: View Solution At5×104bar pressure density of diamond and graphite are3g/ccand2g/ccrespectively, at certain temperature'T'.Find the value ofΔU−ΔHfor the conversion of 1 mole of graphite to 1 mole of diamond at temperature'T': ...
Diamond is used in cutting tools because the strong covalent bonds make it very hard. B. Graphite acts a lubricant because of the weak bonds between the layers. C. Graphite conducts electricity because the electrons between the layers are free to move. D. Graphite has a low melting point...
