    Hey, I don't really know something about nmr ...

    If they say 'what types of protons are in a molecule' then how do i answer that, because the sheet just gives diagrams, but no names ..... sorry if im being unclear, but im soooooo confused

    I don't think I am. ): All of those reagents and conditions are so hard to remember.
    My teacher highly recommend that we learn benzene organic reactions as it it likely to be asked. This is how I learn them. I hope it will help you.
    And to be honest, there's no point worrying because organic synthesis questions only worth 2-4 marks max. It is better to focus on other of your weaker areas.

    Basically you draw with which molecule protons (H+) is attached to.

    Thanks. That's so helpful. (:
    As for my weaker areas...it's writing equations. Like when a question says to write the equation of PbO reacting with acid for example I can never figure out what to put. Unless it's a really simple equation.

    It looked pretty good at first sight. Testing it was another story, it doesn't work... I found a few flaws in it. Your better of learning it the normal way.

    Morning Hmm feeling slightly more panicked than I was last night, but not too bad. Have been reading past papers, but not been reading the questions properly so making silly mistakes, think once I'm more awake it'll be fine though!

    Is the hydrolysis of an ester done with concentrated or dilute NaOH? And is it under reflux?
    Also, what are the reagents/conditions for amide hydrolysis?
    Thanks

    For esters you can use an acid or an alkali, but yes use Dilute NaOH and reflux the **** out of it.
