Do you have the Edexcel A2 chemistry Revision Guide? See how much u have to know from there.

Check it according to the syllabus. ;) But if I am not wrong, you only have to understand the concept well.

I wanna ask about tose points and whether I really have to know specific practical procedures for them or not
eCarry out the reaction of phenol with bromine water and dilute nitric
acid and use these results to illustrate the activation of the benzene
ring
fDescribe and carry out, where appropriate (using butylamine and
phenylamine), reactions to investigate the typical behaviour of
primary amines. This will be limited to:
i characteristic smell
ii miscibility with water as a result of hydrogen bonding and
the alkaline nature of the resulting solution
iii formation of salts
iv complex ion formation with copper(II) ions
v treatment with ethanoyl chloride and halogenoalkanes, eg
making paracetamol.
I need reply plz don't just ignore me :'(

You do not have to do the experiment. Just learn it.
