there's always some mod 8 question where you have to look at nmr/mass spectrum/infrared i think - they either give you a compound and you have to justify it or you have to find the compound (esters or aldehyde/ketone probably since they're a bit harder to narrow down)
and i feel like back titration since there's a lot of steps to think about
in addition to the cycad question there's also that dot point in mod 6 " explore acid/base analysis techniques that are applied by Aboriginal and Torres Strait Islander Peoples" which could come up (i've just been doing trial papers so idk if its been asked in the hsc yet)
