for the test for haloalkanes (where you have remaining two haloalkanes and two alcohols), could you not do: add NaOH(aq) then reflux...this will give NaX (X=halide) for the two haloalkane and then add silver nitrate to form ppt of AgX etc....this would allow you to eliminate the haloalkanes...?
Hi Sir ASAP QUESTION PLZZ: when you have to draw a distillation practical set up. Should the bulb of the thermometer be at the opening of the condenser or can the thermometer bulb be further in the flask but not touching the mixture? THANK YOU!!!
Ryan Yates They have asked for it in the past hence why I included it. I'd hope they would give some indication in the question if they required the making of it

also, sir..why is the ammonia concentrated? it it because so it is in excess?
what does aqueous ro solution actually mean for silver nitrate like how would I imagine it?

Wouldnt the two alcohols have ethanol mixed in, which would give a false positive for both?
You use fresh samples for each test
At 4:26 shouldn't you have written a 2 in front of the oxidising agent, because it is complete oxidisation to form carboxylic acid?
No because you're starting with the aldehyde not the alcohol. Hope that makes sense
as or a2?
could you add 2,4 DNP to test for the aldehyde instead of Tollen's ?
Not really as that just shows it’s a carbonyl
thanks
8:42 shouldn't it be propanoic acid and propanal?
Shakalaka I'm referring to the original chemicals not the products of the reaction
In an exam question, would you have to state how to make the tollens reagent; or can you just say 'add tollens reagent'?

Alright cool, thanks for including it as I'd never actually considered how it was made before!
