The one about the alkane or alkene yeah and near the end...



Hydration is the correct term but I think they will give it for either addition or hydration

Hydration is when u add H^2 not B^2

Weak acid/strong base
I put 8 and 400 for the graph question thing, did everyone use a ruler for the diagram? Our school didn't put rulers out and everyone looked at me like I'd murdered someone when I asked for one haha.

Yeah mine too hahaha, thought a lot more people took it

Think you could have put addition or halogenation, not sure about Bromination.

Was this for addition of bromine across a double bond? Bromination, halogenation and addition should all be correct. Hydration is wrong, that's addition of water

Same :P

For my Physics prelim the hall was packed, compared to my Chemistry exam and prelim. I thought more people would take chemistry
