This is a chemistry question that i found tough....

Suchal Riaz I am working on compiling the questions that i found tough..... some of them are just plain out stupid and also I haven't done many papers until yet.... but i'm starting to gather what i find difficult for this thread... it may be a little slow but it will come.. sorry for the delay man but this is a great idea u came up with.... (Y)


a) acidities: CHCl2CO2H > CH2ClCO2H > CH3CO2H [1]
due to Cl being (more) electronegative/electron withdrawing (than H). [1]
this stabilises the anion or weakens the O-H bond





c) (iv) [in addition to the answer.. sidbloom explained this part to me]
benzene rings form rigid structures and make the polymer less flexible
so in order to make it flexible, make it into a cyclic acid or remove the double bond in the benzene


hope it helps

Physics P4 ___ s12, p42

All else is doable but (b) was a little tricky and stuff.... do try

some of these so called worked solutions of hardest questions

 

[Ishaq]

Does anyone knows/can list down the years which had the most difficult papers? For P3?

So far I have seen, almost every year has atleast one hard question!

 

[David Hussey]

This is only for Science i guess?

Well yeah. I just got hold of a pdf with all p3 papers compiled. Now I'll just skim through it regularly and pick out questions that seem difficult/tricky.
