Sir, you are saving me with these past papers! Please do more! I beg you!!

[abeehafatima]

you should do both paper 1 and 2. and thanks for your efforts really appreciated. It is really hard to find good chemistery 9701 video thanks for providing with videos

[media]

sir dont you think question 1 a was very unclear ? most of my classmates and i thought we had to answer from the 3 species they have listed as they didnt ask for definitions, they asked us to IDENTIFY the SPECIES..

[zestyolu]

Thanks for the video and good luck with your exams!

[Uzunars]

Just a small correction, in 3B.ii. The repeat unit for the polymer after the double bond you attached CHCH2CH2OH, instead it should be CH2CH2OH because the CH is already drawn

[luvfoood]

In question 3(a)(i) for the last one to distinguish between D2 and D1 can I use acidified dilute aq KMnO4 since only D2 will get oxidised and turns colourless as it’s a sec alcohol and D1 will not change because tertiary alcohols cannot be oxidised?

[alphagaming]

21:20 sir can the dimers be opposite like how you did it but reverse?

[ikrash]

Thank you sooo much for this! Also you sound like Abed from Community

[Uzunars]

I really hope your channel grows further man. You are extremely underrated, thank you Soo much for taking time off your day and helping a bunch of students

[zaynabbb]

Hey
In the last question, cant we add k2cr2o7 directly to the aldehyde to change it to carboxylic acid, instead of changing it to alcohal first?

[CallumSamLukeBenSmith]

For Q3c) iv) isn't the bromine added to the central carbon because the methyl group will have a positive inductive effect?

[oluwasegunfunmiafg]

Thank you so much But since ALCL3 Can be either ionic or covalent then I feel it's better we go for "Giant" since it's not possible to have simple ionic and also because Aluminum as a metal is giant metallic so it'll basically form Giant structures with other element in period 2 or 3 .. Al2O3 for example is Giant ionic!
Thank you so much 🥰 though because you explain things so well please do more of papers for P1, P2 and P5.

[phumizamela]

Thanks so much! Your maths is impressive ❤, and you’re very sweet..

[shahnarifan]

sir which is a better reducing agent to answer questions
LiAlH4 or NaBH4 which one can be used more often
and thankyou so much the videos really helpful

[jaanneeee]

Thank youu soo much sir. please do more of paper 5🙏🙏

[sarazannab]

small correction: in Q3 (v), the product is C3H7BrO2.
thank you!

[JudeWeraduwage]

Jeez, the marking scheme can be wrong? How often does this happen?

[CallumSamLukeBenSmith]

Thank you so much for all the videos, they have helped my mark so much. :)

[delmau]

Thank you so much, I appreciate you a lot

[Leo.tae]

Sir in question two there is no mistake in the marking scheme, I searched about at and they said that Alcl3 has an ionic bonding while Al2cl6 has covalent with a simple structure, and also focus on the point where they said at room temperature
