Scroll to see replies

would HNO2 be fine? they accepted either in mark scheme ?

and the other one i put under alkaline conditions

the question on the NH2 going to NH3+CL-, the reagent was conc HCL(aq) ? cause it said reagent there was no s at the end ?

I put this too Otrivine, I hope it's correct!

Don't think you needed conc.

But depending on the MS and how lenient OCR are this year I think you had to put HCl(aq) rather than HCl (could still be accepted though). Well done for getting that.

I think so. I'm going off now before I discover anymore mistakes that I might have made.

Your A2 coursework does count towards the A*. F324 + F325 + F326 must equal or exceed 270 UMS and you need 480 UMS overall.

oh okay thankyou :smile:

how did you think it went

1 exam left! Just FP2... *cries inside*. I hope that Chemistry has gone ok... I've gone so paranoid, discovered 3 mistakes so far which would correspond to 5-6 marks lost, I've probably lost more!

Yeah, didn't put concentrated just HCl, should be hopefully.

I don't think the N2+ was replaced by the iodine. If you looked at the structure you'd see so. :/
It had an OH or something I think too.
I'm not sure, I'm probably wrong.
