Did you get C12H26 for molecular formula?
yes!

What was the cracking and reformed after cracking and
The effect on engines improvement or something like that

in general, i wouldn't say that paper was easy, but manageable. Multiple choice was tricky, much harder than in previous years. when doing the energy density question i thought edexcel ran out of "hard" questions lol
did u actually see the jan 2015 paper mcq they were 100 times harder than these

Can't remember which compounds but I put more efficient combustion too

what were your isomers ?Original post by baebae
guys did you have .24 for the last question?
yeah!)

yay! what were your isomers ?
what were your isomers ?I think A and C? I remember it was C10H22 I think, said it had same molecular formula (same number of carbon and hydrogen atoms) but different structures.... maybe overkill but I couldn't remember the concise definition and I didn't want to lose marks :")
