I think the exam asked to add H-Cl to Methanol, so it would have been nucleophillic substitution as the H-Cl has a permanent negative dipole which will attack the positive carbon in the methanol
But what you said about the alkene and halogenoalkane is correct

I think it was 3 marks so i wouldnt worry about it I found the paper quite hard overall due to the numerous GCSE questions that i hadn't done for 2 years... How'd you find it overall?

i thought it was a halogenoalkane undergoing n.sub with OH-? i feel like ive missed so many marks i dont even remember if i underlined nucleophilic and substitution - like i remembering choosing them in my head but i dont remember underlining them... 5 marks gone then
Im just scared its going to be one of those really fussy OCR things that they do like not accepting peptide for amide :/
Yeah but I sincerely doubt this will be one of those things, the only reason why peptide isn't accepted is because we're not taught peptide in chemistry and the technical, chemistry name is amide. Since it's just quoting stuff from an article I think they'll be fine about it.
what did you put about infradred spectrum and how co2 can be identified?
You had to mention that each compound have a unique fingerprint region and looking at the bond absorption if C-O is present then it tells you there is co2
What did people get for the difference in density question???
I said that Ice is less dense because when water freezes bonds get closer together leaving empty spaces so that the density of water decreases or something along those lines and you also had to talk about the formation of hydrogen bonding

I wrote about absoprotion in due to c=o bond and each bond abosrbs a specific frequency of IR .... something like that
I was going to talk about the FP region but a question was asked about it later.
I don't think it was an Alkene input Nucleophilic sub cause I remember it had an alcohol attached to it and at the end you got methane chloride and water
