That first question almost made me laugh

 

[SadCeliac]

That was such a nice exam, kinda annoyed I didn't get the MgF2 precipitate question but whateverrrrr I'm done hsc

 

[SadCeliac]

Oh also was NH4Cl a Brønsted-Lowry acid

Because it acts as a proton donor and it's the conjugate acid of BL base NH3

NH3 + HCl --> NH4Cl
And
NH4+ + H2O <--> NH3 + NH3
shit I don't think I did this second equation lmaoo

that sucked

paper (some questions missing)

maybe better version coming later

Tywebb some questions are cut out (31-36?) fyi (I assume you know)

Yeah I'm aware of it. Maybe better version is coming later.

Cheers - will look out for it

Did we have to name the compounds? Or just say their functional group

 

[yepImhere]

that sucked

Yeah I did very average cause I only half did so many questions and the 9 marker omg

Just the functional group

lmao the 9 marker, I only recognised it due to the catalyst
Yeah I am the same I only did half for a lot of them

About the very first question.

Were both the answers Methylprpanal and butanal?

Because Ketones and Aldehydes are seperate funtional groups, and Butanal and Butanone would be a positional isomer, not a structural isomer

I got butanal and butanone for the functional group isomers and butanal and 2-methylpropanal for the chain isomers

YOu couldn't look at the IR points and the NMR to back up your points? I mean, I can understand for the last one, but the top two weren't that hard.

Not trying to be arrogant if I came off like that

Oh crap

 

[dsakvyilsa]

i fucked up the 9 marker HELP i did propene propanol propanoic acid (i originally had propanone) 0 atar coming soon

BUT I DONT EVEN CARE BECAUSE IM FINALLY DONE

seems like a lot of us finished today on chem lol,
feels like nobody here does physics???
