    I can't believe after being stuck on entry for 20 minutes I've got a best ever finish of 39th!

    Snake's top hints:

    Entry: Think about symmetry.

    Copper: What is the molecule's image made up of? Does that give you a clue?

    Silver: Look very carefully at the peaks and more importantly the scales on the axes.

    Gold: This is the hardest of the lot. Research IR spectra and how they work, I guess.

    Rg: You need to be able to calculate the volume of the arena. The rest is a bit of clever maths, but the website accepts a wide range of answers, I think. Keep calm!

    These are just clues. I won't be posting any answers directly into the thread.

    Entry
    The third picture on the top row is a good clue. Remember, this relates to chemistry, but not exclusively.


    Copper'
    Either count the molecules, or just look at the picture, should give you what you're looking for. Then what is lambda usually?


    Silver
    Should recognise the graph from AS chemistry, should be a doddle from there with a google search.


    Gold
    Your best bet is to find the significance of the numbers - to do with the bonds, but not just as simple as counting them...


    Rg
    Simple maths, just make sure you take care of your factors. :sad:

    Someone got the answer for silver? I know exactly what it's asking, now the question is just becoming irritating.

    I give up now. Researching IR spectra at 1AM is only fun for so long. Night!

    didn't like the last book as much, didn't live up to my expectations
    thanks for the tips and to snakefingers as well they're really useful, i proceed onto gold

    I have to say, this challenge wasn't bad. But Rg is a little misleading at first. Did they have to use a minus sign? O2 doesn't even have single bonds! Honestly cambridge could've been less sneaky and have used an equals sign instead.

    I'm stucked in silver. I know what the graph is but it keeps telling me:
    Almost, take a closer look at where the peaks are...
    Help!

    For all those stuck on gold, look at the basics of IR spec theory.

    I don't know how to say it without telling the answer, it is a property related to symmetry (or asimmetry) it is related to stereochemistry as well....
