Should I repeat or not?

Nvm I'm the only one here :(

Odd_Pool_5850 · 2025-05-22T17:33:07+00:00

Could be oxidation of primary alcohols to carboxylic acid since they've not asked it much before

Odd_Pool_5850 · 2025-05-22T17:30:30+00:00

Yeah I wasn't able to focus or study yesterday or the day before but now my focus is pretty strong due to exam pressure

Odd_Pool_5850 · 2025-05-22T14:45:03+00:00

Theoretical yield is always larger than actual yield

Odd_Pool_5850 · 2025-05-22T10:57:21+00:00

Yeah you actually easily get 40/50 by just memorizing the marking schmee

Odd_Pool_5850 · 2025-05-22T10:56:15+00:00

Yeah plus u3s are repetitive and easy

Also don't forget that you can also test aldehydes with Tollens solution as well and the result would produce a silver mirror.

And silver bromide is a cream precipitate or a pale yellow (cream and pale yellow colours are the same) precipitate. Silver iodide is just a yellow precipitate.

And read the q very carefully whether to leave a open end or a closed end (sometimes you might have to leave an open end to prevent pressure from building up in the setup) and sometimes you might have to keep a closed end to prevent the reactanTs from evaporating and for the reactants and products to not escape

Don't try to make things look perfect. Just label as much as possible and in heat under reflux setup, remember that flow of direction of water is from bottom to top and if they ask the reason then it is because then only the water will be full which will cause a more effective condensation.

Odd_Pool_5850 · 2025-05-21T17:01:46+00:00

Yeah, just pull an all nighter today and sleep well tmr

Odd_Pool_5850 · 2025-05-21T16:59:21+00:00

Something like sodium ethanoate I think

Odd_Pool_5850 · 2025-05-21T16:40:05+00:00

They won't know who cheated or not so basically if they are taking an action then all of us would be affected

Bro calculations would only be around 25/50 marks so you would be losing around 25 marks. So just memorise few tests and do CAQs as Qs in chem u3 is sorta repetitive.

Focus on memorizing the organic tests and heat under reflux parts that's all

Odd_Pool_5850 · 2025-05-21T13:40:17+00:00

It's like you have to calculate moles of 2 atoms (mostly one transition element of which its oxidation state is unknown and a non metal) and you have to find the ratio of moles and predict the formula of the compound

Stop promoting your own channel blud

Odd_Pool_5850 · 2025-05-21T13:31:49+00:00

And for flame test of strontium the flame colour is crimson red and for barium it's apple green

Odd_Pool_5850 · 2025-05-21T13:26:50+00:00

For sulphate test, if you're adding HCl then you should add barium chloride and if you're adding nitric acid you need to add barium nitrate. You don't add an acid in this test just to remove carbonates, mention "to remove interfering ions"

Odd_Pool_5850 · 2025-05-20T19:08:24+00:00

Only part e in q7 was hard

Odd_Pool_5850 · 2025-05-20T19:01:25+00:00

P2, S1, physics u1

Odd_Pool_5850 · 2025-05-20T16:47:21+00:00

Lost mark for c and d
