    Like otrivine mentioned, it can be used for testing for anabolic steroids in atheletes. It can be used in forensic sampling, by analysing and identifying substances found at a crime scene for example, it ,can be used for space exploration in space probes or analysing pollutants in the environment, checking for the presence of pesticides in food, or assessing the quality of drinking water and waste water

    Okay, thanks for these, hopefully they'll only ever ask for two uses in the exam.

    Acid hydrolysis-
    Heated under reflux with an acid for 24 hours,
    Possible reagent HCl

    Alkaline-
    slightly of 100 degrees, and in the presence of an alkali.
    Possible reagent NaOH

    Yes, but for acid also mention the concentration of HCL, which is 6 mol dm-3

    Oh okay, will look back at that!

    Give 3 methods which will prepare products with only one chiral isomer.

    Use biological enzymes (catalysts)

    use transition metal ion complexes


    chiral synthesis

    Nice one, though don't forget 'pool' in chiral synthesis, as chiral pool synthesis, because chiral pool synthesis improves the efficiency chiral synthesis.

    In the book, it does not explain each detail?

    true!

    describe thalidomide
    Thalidomide has two chiral isomers, one of which causes birth defects in infants, and the other which cures morning sickeness and colds and flu's
    Thalidomide is a chiral compound.

    Haven't start re-revising yet...... -______-

    BUT by mark my words by Sunday 21st (next week) I will have Mod 1 Mod 2 and Mod 3 done.

    Once I dispose of this Chem 5 and Phys 5 revision.
