    you can reduce a nitrile, (LiAlH4 dry ether than hydrolyse with H+)
    hoffman an amide (Br, NaOH and reflux)
    substitute an alcohol or halogenoalkane with NH3 in dry conditions,

    what about reduce an amide by LiAlH4 in dry ether, and hydrolysis of an amide by heat under reflux ?

    we only need to know dehydration and degredation of amides, one forms a nitrile and the other an amine, for edexcel at least..

    how do you get from a primary amine to a primary alcohol in 1 step?

    Lalalalalalalala don't need to know this one **smug look** but it may be useful? OH- reflux? Most things like this tend to be?

    which exam board do you do?

    I do edexcel... apparently you have to react it with NaNO2 in acidic conditions or something?

    correct, the reaction between nitrous acid (NaNO2/HCl) below 10ºC will change a primary amine into an alcohol via the diazo salt intermediate (cannot be isolated in this case)

    good ...also, how can the Nitrogen on the benzenediazonium chloride have 4 bonds?.

    C6H5-N=N+ is in resonance with C6H5-N(+)=N

    the lone pair on the central nitrogen (left hand side) moves between the two nitrogens to give the structure on the right hand side

    The actual structure wil be a resonance hybrid of these two

    There is no problem in nitrogen having four bonds developing a positive charge - just look at the ammonium ion NH4+

    Oh do have to know that benzene one - I'm doing salters and its part of the azo dye chain...mental note to self. N with four bonds - one of them is dative covalent, coordinate if you will. usually to a H+
