    I think I got all of Q2 wrong. All of it. I did the preparation of ethanal as a reflux, which it's not.

    Didn't attempt the second part of the question, new the first answer was clove oil but we never even did that experiment in school.

    The preparation of Ethanal Is a reflux i thought??

    Nope, the Ethanal is allowed to boil off.

    It's a distillation. You want to boil it off before it can oxidise again to become ethanoic acid.

    I reckon we might get 6 marks out of 30 for it?
