Yeah I found that too. Overall it was good, fairly straight forward and good grade boundaries. Wasn't it 84 for an A*!

Was like 83 I think! Really low. If the actual exam is like this, i will be a happy man.

The questions tend to be quite repetitive, there's not a lot of scope for what they can ask you :tongue:

Good thing for us though, if you know it inside out :biggrin:

Same. I think the revision guide explains more than the textbook. It's really helpful!

Does anyone know how you'd name a benzene ring with an amide group attached? :s-smilie:

Thanks!

Sorry I should have explained better, the benzene ring is attached to the carbon, not the nitrogen, so it wouldn't be an N-substituted amide.

So something along the lines of:

C₆H₅CONH₂ ?

Apparently it's just called Benzamide.
