    Advantage: easily combustible so little cost and time spent on burning the fuel compared to other fuels
    Disadvantage: non renewable resource and its combustion releases harmful pollutants into the air, i.e carbon particulates which affect breathing in people with respiratory problems.

    But how you know the pros and cons? They are not on the Chemical Ideas book and on the the chemical storyline book there is a lack of detail.

    i know them cos of GCSE chem, tbh they are more likely to ask you about the pros and cons of hydrogen, LPG or diesel which are in the specification and the storylines.

    See the past paper questions of fuels and their pros and cons. Their mark schemes are very concise and annoying.

    aren't they always, bugs the hell out of eveybody , what i tend to do is get worried that i haven't written the key word and so i start writing everything i know about the topic in the hope that something i've written will get me the marks i desperately need but then you get a load of timing issues i've resorted to learning mark schemes now

    yeah, with the long questions on shapes of molecules I do a similar thing. I say "regions of electron density repel as far apart as possible" first so I don't forget. Then I say how many regions there are...

    This is my third time, I absolutely cannot stand this paper. I'm aiming for an A* overall, so getting 90% in this paper is a must.

    Does anyone know how picky the examiners are with the mark scheme? For example, I always say groups (note- not pairs, GROUPS!) of electrons rather than electron density. Some mark schemes say allow it, others don't mention it at all. I've never seen one specifically disallow it. I'm aiming for over 90% as well, so I can't really afford to drop stupid marks like this :L

    they are ridiculously picky to the extent that it's a piss take, did a paper and was asked about what spectra produced coloured lines on black background, i wrote emission spectra they didn't accept it, the answer was atomic emission spectra! just goes to prove that the difference between an A and a B could be 1 silly little mistake like that, puts a lot of pressure on a person :/

    Unfortunately, my teacher is being a pain in the arse and wouldn't give me the f331 june 2012 paper. So, when he went to get a coffee, I went on his laptop, opened up the pdf and quickly wrote down some of the answers. Phone was low on charge but I took a few snaps. I'll take my usb in tomorrow and have it up asap. I was going to upload it to this site directly from the laptop but I was scared that I might get caught if I logged in and so I deleted the history.

    Here are some of the answers I managed to get:

    1(b)(ii) (molecule) has broken (up/down)/fragmented OR two or more electrons knocked off

    1(c)(ii) Bond angle = 90, Six
    regions of electron density
    around S/central atom Octahedral

    2(a)(i)
    alcohol
    alkene

    (ii) C9H10O

    (b)(i) Fractional distillation
