ha, i looked at that 7 marker question for 15 mins and though "WHAT THE FUCK???" then with 15 mins to go in the exam i looked again and went "ahhhhhhhhhhhhhhhhhhhhhhh, now i get ya, simple!" so i had only half a page left (righting bullshit stuff b4 to try and scum 1 mark from it) to write about all the stuff and then i did diagrams on top of me diagrams to show the reflux and distilation and bla bla bla. i also couldnt remember if it was an ester produced cause i forgot what an ethyl butanoate was, so i guessed an ester and got it right! so then i had to go back and change multiple coice! nother mark collected. but i dont recon u needed that much detail for 7 marks, i mean with 3 things to talk about and only 7 marks for it, it must only want a broad description, and many people wouldnt have even worked out what the question was. i thought it was some type of polymer at first, lol. over all though, went into chem with shit all study thinkin id fail, walked out very happy indeed, that first place i worked for in assessments wasnt wasted in the end!
