i kind of remember the question!? i think i put hydrogen bonding

yeah I put hydrogen bonding as well, due to that -OH group on the compound.
for that agricultural methane source, I put cows' waste gases, is that wrong?

same, i never learnt it so i got them wrong.

yes

Put way too much time into revising for this and it turned out the paper was easier than usual, what a waste of time! Should have been doing maths revision instead.

For one of the questions " name the type of bond breaking that occurs" i put "homolytic rather than homolytic fission" would that loose the mark ?

I'm not sure. Because i think in what we study the only homoytic is fission. Not fussion, but tbf you probably didn't get the mark. I am sorry.

I researched past questions like this and the correct answer was, as quoted in the mark scheme:

"Homolytic (fission) / homolysis"

So fission probably isn't required for the mark.

I think it will depend on the discrepancy of the examiner.
