well, i think i know enough, like about naming them and what not. they might also ask about the differences, like symetrical differneces, i can't remember the exact word.

i would also put my money on comparing the heat of combustion of three alkanols for that reason as well...
I think they've already tested comparing the heat of combustion of three alkanols???

ok if anyone wants the cfc equations here they are:

CCl3F --> (uv light) CCl2F + Cl
Cl + O3 --> ClO + O2
2ClO --> Cl2O2
Cl2O2 --> O2 + 2Cl (this Cl can then go back to step 2 and continue the problems)
