fullerenes !!!!

can someone please explain to me everything i need to know about fullerenes ? as weird as it sounds the internet didn't help me at all, if anything it confused me :frown:

and can someone please answer this question:

Diamond and graphite are well known forms of the element carbon.Other forms of pure caron have been made.They exist as individual molecules of different sizes and are called fullerenes.The main fullerne has the formulae C60.

a) how does the structure of a fullerene differ from that of a diamond ?

b)why is an atmosphere of helium used for producing fullerenes ?

c) describe a chemical test that could be carried oput on a solution of C60H36 to show whether the hydrocarbon is unsaturated or saturated ?

i think the answer to c) is that your do the bromine water test ??

thanks x

I think pretty much the only thing you have to remember about fullerenes is their structure/bonding. Parts b and c are from knowledge in other parts of the course.

a) is that diamonds have covalent network bonding structure vs fullerenes covalent molecular.

b) is just knowing that the carbon would react with oxygen if it were present instead of the helium.

c) you're right about bromine water.
