    I put silver nitrate in aqueous solution. Forming white ppt for the halo alkane and nothing for the acyl one.
    AgNO3 does react with acyl cholrides tho

    i thought that the acyl forms the white ppt, not the haloalkane

    Did anyone get 1st and 2nd order for the rate equation question. The numbers were so awkward.
    I did 😁

    Can't be, it said it reacted to form a green solution with acidified potassium dichromate (VI) so it can't be a tertiary alcohol.
    But what I did get was similar: CH3 - O - C (CH3)2 - CH2 CH2 OH
    wasn't the OH a singlet? In this case it would be a triplet. Not sure tho..

    They normally accept a range of answers for reagents.

    For the acid (acyl) chloride the simplest (in my opinion) was:

    Reagent: AgNO3
    P: no visible change
    Q: white ppt (of AgCl)

    What did you get for number of carbon peaks?
    9 but I didn't have time to check so it's probably wrong

    Do you think Ni/H+ in ether will be right as well for step 4?
    This is an extract from a previous mark scheme. And it shows what they accept for both steps.
