    Did your teachers give you the Practical Skills handbook?

    http://www.ocr.org.uk/Images/70646-p...s-handbook.pdf

    Pages 28-33 are seriously useful/important for the evaluative paper.

    Wait did you have it yesterday? If not

    Basically there is nothing on mass spec

    You need to know limitations of infrared spec
    You need to know how to calculate percentage error for burette volumetric flask and pipettes
    You need to know how the mean titre will change if you make mistakes in your titration
    You need to be able to draw e/z isomers
    Remember the reactions of alcohols
    Remember the test for unsaturation
    And you need to be able to write equations for compound with more than one functional group reacting with metals
