    P was a ketone, so it has no visible change.

    Q would also have no visible change with Tollens' so it cannot distinguish them.
    Dammit, well at least I know now I guess!

    Did anyone put an answer as nucleophillic addition and for another answer nucleophilic addition elimination and also did anyone put 1-chloroethanoylchloride for an answer? Worst exam ever
    It would be 2-chloroethanoylchloride.

    Ok so for the last question we know it has to be a primary/secondary alcohol because of the dichromate reaction, but the O-H nmr peak was a singlet, suggesting the adjacent carbon to the alcohol group is itself bonded to no hydrogens. Therefore how can it be a primary or secondary alcohol??
    O-H peaks are always singlet as it counts protons attached to the O not the nearest C

    Yes for all except last one.

    C=O takes priority so you count from this carbon, hence it should be (I think) 2-chloroethanoyl chloride

    You dont need H+ Ions you puppet you arent making a hydroxy nitrile
    I know 😭😭😭😭
    He problem with this paper was that We had no time to go back and check answers because of the volume of 1 markers that took ages to figure out. 😭😭😭 Guess I am doing agriculture. 🌷🍁🎍🌿🌴🌳

    Edit: oops, misread your comment.
    what are you talking about you dont need to form HCN you just need to form the nitrile which is done by KCN as the nitrile group subbed the Br there is no need for H+ Ions unless the compound was an aldehyde or ketone and you wanted a hydroxy group.

    But that wasn't the question, so all that was needed was ethanol to catalyse
