AQA A-Level Chemistry June 2017 Paper 2 [Walkthrough and Tutorial]

[@kimygxx]

For 1.2 when it says condition why would it be excess NH3 (I know it says that on the mark scheme) but is that not a reagent rather than a condition, isn’t condition more heat/pressure etc?

[@the-a-level-cookbook]

you can say in excess as a 'condition' as well, the reagent is NH3 and it's essential to use it in excess to get it to only form that primary amine

[@montymahal7894]

for 1.5 can you use KOH instead of NaOH

[@Sssafdar7892]

Yes!!

[@HGg-zv1di]

In the future could you actually do the paper rather than skim reading the answers from the ms with half-arsed explanations, its a common theme with these walkthroughs and u make frequent mistakes because you rush things :/ QUALITY OVER QUANTITY!

[@the-a-level-cookbook]

as mentioned before - the rushing is bc I'm trying to do as many as possible for people to use in the meantime and these will be redone at a slower and more improved pace. in regards to the 'half-arsed explanations' - the point of these videos isn't to sit and explain an entire topic for each question, nor is that even needed, the point is to explain the techniques on when to do what for each question/how to get around having to think "I wonder what topic this question is asking" - also I don't skim read the mark schemes lmao I do them and chop out the bits where I get it wrong bc why would I put that in the video lmao
I appreciate there are mistakes but they're cut out to the best of my ability and all answers are checked over on the mark schemes too after

[@the-a-level-cookbook]

and with all due respect, this is a free resource I'm taking the time out of my day to do, especially given that I work as a tutor and am starting work as junior doctor soon, and I really do not appreciate being told these are 'half-arsed' and "QUALITY OVER QUANTITY" - the channel and descriptions all include a disclaimer saying that these arent the gold-standard and perfect, and errors will be present - that's just inevitable. I'm a one-person team doing every single part of this project. Perhaps maybe considering that rather than being rude would be beneficial in the long-run.

for q6.4 where does the cl go

[@Sssafdar7892]

Forms HCl as a byproduct!

[@Sssafdar7892]

Oh wait he forgot to put an arrow going from the bond of cl to cl so the cl needs removing to form HCl at the end

[@lokhinong1020]

quantity over quality, u got a few marks missed and wrong sir.

[@the-a-level-cookbook]

i'm aware - hence why the disclaimer's there in the comments, these are just quick walkthroughs on thought processes/exam techniques + i'm planning on redoing these slowly over time as well
for now and my current pupils, im doing this for them

[@EctoNecto]

For 6.2, can you not remove the proton from the alcohol group, making both oxygens negative?

[@the-a-level-cookbook]

alcohol groups can't act as acids, they don't lose the H+, only the carboxylic acid bit does

[@EctoNecto]

Ahh thank you
