anyone else found the 1st 6 marker hard (obvs the second one too)
that paper was so hard and edexcel grade boundaries are always so damn high

No, that is nucleophilic sub

Thought it is electrophile sub

That was probably, by far, the worst paper I did

Thought i was the only one looking back ar the test i did i realised how many marks i lost
No it’s nucleophilic

It’s electrophilic sub because it’s the reaction mechanism for benzen

Same I found the 6 markers hard!! I doubt it will be much higher than 82% for an A* and like 70% for an A though...
I put that there were 4 chiral molecules and then stated that there were 2 optical isomers... Correct?

To work out the bromopropane I believe I converted to moles then divided by 31 and multiplied by 100 to get total moles of the original. Then converted to whatever..

Its electrophile cus there are an ions is attracted by lone pair of nitrogen

i did exactly what you did
It wasn’t it was the amine group on the benzene that was reacting not the benzene

For the paper ...
Its not, it literally says it reacts by the same mechanism as ammonia and a halogenoalkane, which is nuclophilic sub

I mean people are saying it was easy so i actually don’t really know but what do you think?

Still, electrons of amine attract ions so it is electrophile sub
Is there supposed to be?

Lol noone got anything to do with optical isomers ????

Oh lol

The ions are attracted by electrons so it must be electrophile ?

I think... they ask about 4 structure of the alcohol ?

ikr but it is definitally it depends on how may marks people get though for the paper
