Okay, the preparatory problems are on this page http://icho2013.chem.msu.ru/materials/Preparatory_problems_IChO_2013.pdf
. Whoever wants may post his attempt on a problem, so we can all together check our solutions. I will start with the first and half of the second problem:
-bigger distance between the layers, so they can be easier separated;
-the carbon atoms attached to oxygens are more reactive that the regular atoms in graphite and they can easier undergo reactions during the synthesis of graphene.
-you have to remove oxygen.
2. x=0.375, xmax=0.5;
3. -OH, -COOH, -C=C-, -C-O-C-;
4. I got 34%, but I don't understand the part with upper and lower limit;
1. ΔH=-467.5 kJ/mol, ΔG=-454.5 kJ/mol, Nγ
Anyone got somewhere a similar result? If not, where is the difference?
