    Which is the correct order from lowest to highest field for the chemical shifts of the numbered sets of protons in the H NMR spectrum of this compound..


    BrCH2OCH2CH3
    ^A ^B ^C


    Okay..the right answer is A<B<C. I thought the right answer was C<B<A
    I thought the higher the ppm the higher the field..so then the H's in the middle of Br and O would be in the highest field and the H's on the methyl at the end would be at the lowest field?

    oh yea So highest field=downfield? In this question they said highest field..not highest numbers. So, I should just go with

    highest field=lowest numbers=upfield.

    lowest field=highest numbers=downfield


    :idea:
