    What's your question?

    1. Pentan-3-one will be produced, as it's a secondary alcohol.

    2. Never come across basic K2Cr2O7; usually acidified with dilute H2SO4.

    Given that it is an oxidation reaction, however, I'd go with propanoic acid.

    That would be a good place to start! The question.

    "For the following reactions predict and NAME the main products formed"

    I have a few more, if you could help...

    3. Ethyl methyl amine with cold Nitrous acid

    4. Phenol with concentrated Nitric acid at room temp.

    5. Methyl benzene with concentrated Nitric and concentrated Sulphuric acids at room temp.

    6. But-2-ene with bromine water at room temp

    7. Salicylic acid and Ethanoic anhydride at 85 degrees celsius

    8. Propanamide with dilute Sodium hydroxide and pure Brominee Br2 at room temp and in the fume cupboard

    Any help appreciated

    Thanks
