I guess just b4 exams its normal for any1 to anticipate the topics coming in any paper!!
Its quite possible to predict from previous past paper....i didn't get the time to collect the topics and predict for A level chemistry paper 2 on 4th nov (Wed.)
If u guys got some thoughts on topics please share....lets predict together! I don't think thats cheating right??
-
revise ur group II vry well!!
knw all the equations/reactions...
n am fnkin on electrolysis n reaction kinetics...
wat others r suggesting????????
-
wat about the organics guys? always qs on organics...and they are usually the hard part of the exam :-\
-
I haven't finished the syllabus of chem yet, gonna go through organic / inorganic / equilibrium / kinetics and that gas law thing.
fml
-
bt 2moro its jst p2(mins the As part)
so 4 organic we jst nid 2 knw reactions/reagents n no aromatic cmpnds

chk it out!!!!
-
what else..?
-
organic..all basic reactions are imp...
i guess one Kc question might b der...
isomers of esters,alcohols...
aldehydes and ketones..etc etc...
i guess these are imp from my p.o.v.
-

..........
I don't think Kc ques wil b there as 2copies of Kc question came in m/j '09 paper 21 & 22 (ie. 1st & 2nd variants
Oh By the way.....Is there going to be 2 variants of paper 2 this time too??? Exam timetable jus shows paper 22 for chemistry no paper 21.... :-\
Do u guys think they repeat topics in 2 sessions of same year?? maybe theres a pattern from other pastpapers of 2008 or 2007

i dunno about d probability of it cming...just tht its imp...my chem teacher tld me so...anyways with AS im not leaving anything cuz i think d papers are really unpredictable....Kc isnt tht big a topic...so mayb a small quest cud also come...i dunno ..im jez guessin aftr all...
i think variants are goin 2 b der..i heard my school principal toking bout them....
i tried my best to find patterns...lol... :(no such luck...
-
i fnk this tym also thr is 1st n 2nd variant ppr...
cz in ma tymtable thrs p21

People we need to discuss chem ! ok anyways wats.
Q. Define Ionic radius ?
Q. tell me all you can tell me about complex ions ?
Q Al2O3 + H20 -> ??????
Q.Al2o3 +NaOH -> ???
-
Haha group 2 aint in As!!
maybe u mean periodicity?..
neway revise all chap for tomoro...
-
Lol dude group is in as ,as in if your talking about cie tht is!!
-
Haha group 2 aint in As!!
maybe u mean periodicity?..
neway revise all chap for tomoro...
mann you scared me..i checkd my syllabus again..grp II is der...
all d reactions and everything is der....i was studying group 2 only rite now...*sigh* and i thot i wasted my time....
-
yeah the AS group 2 is huge! A2 part's group 2 is small...
Anyways lets hope this time paper2 will b easier...as last time it was tough
Easy chem practical paper33 indicates next papers would b easier =P
What u guys think?? I think something on chem energetics mite come
-
omg
what did you guys find hardest in the paper?!

Q.Al2o3 +NaOH -> ???
1 - distance from the nucleus to the outermost electron
note:- Al2O3 is amphoteric so it can act as both an acid and a base depending on wat it reacts with. so acid + base = salt + water
3 - Al(OH)3 + H2O ==> got this from wiki because i wasn't sure
4 - NaAl04 + H2O
-
3 - Al(OH)3 + H2O ==> got this from wiki because i wasn't sure
Al2O3 + 3 H2O ? 2 Al(OH)3
the one u wrote was almost correct, do be careful dat u can't have H2O on both sides of da equation
-
omg
what did you guys find hardest in the paper?!
omfg the first 2 questions were a killer..

sorry dude.. can't say til maybe tmr...
-
ah cmon dude justt help me out with sum equations and hard topics...like i suggested dose

Q3. Al2o3 does not dissolve in water because of high lattice energies.
Q4. Al203 + 2NaOH + 3H20 -> 2NaAl(OH)4
-
thanks man ill reputate u but can u explain high lattice energy stuff a bit more and....wat do u think i should study cause i am goin 2 write in 30mins
-
Is there a question on Kp or Kc?
-
and organic man dat kills
-

i'm so sorry but u just have to find out when u sit for it..
-

haven't learnt about that.. its in A2 i think..
-
what you write for q2 sor?
-
My friends just had their exam today. And FYI, they said it was surprisingly tough. Beats me, I'm Chem-less :D

well then hopefully they lower the grade threshold :-\
which paper are they taking By the way? variance 1 or 2?
-
variant 1 /....a minute left any hard stuff please man please
-
variant 1 /....a minute left any hard stuff please man please
ok can't help then.. i did variant 2
-
i knew u wud say dat i am doing var 2 aswell pleaseee help
-
No idea. They didn't tell me. All I know was that it's tough D:
-
it was a lame one, I had to pee in the middle so I lost time; thus couldn't finish.
-
I thought it was extremely tough. There wasn't ANY equilibria and all. Those are usually easy marks. No electrolysis. 3 ORGANIC QUESTIONS!
ps. i'm talking about variant 2

same here then.. yeah it was really tough right!!! i think the organics for q4 and q5 was okay, but question 1 and 2, esp 2 was extremely difficult.. scare the hell outta me when i did it..
-
i dnt know what variant i did..it started with defining isotope.. but man the last 3 marks i lost it..and i never revised the free radical reaction..it was ok though
wats the max mark u lose in THIS paper to get an A??
-
oh that's variant 1 then.. so apparently variant 2 is harder.. :'(
depends on the grade threshold..
for may june 2009 it was pretty low.. 42 marks to A..
but for one of the 2008 paper, 48 is required to get A :o
hopefully this time the grade threshold will be low..

That's variant 1

i did this variant
i think i did well
-
evry thing was hard .... :'(
i messed up wrote radium hydroxide for insoulble
wrote wrong observations
didnt get d enthalpy write and organic was hard 2.
-
so i guess i oviously had variant 2...just my luck..lol
i knew all d free radical thing n stuff... :-[
hope they lower d threshold.. :-\

No you did variant 1.
-
No you did variant 1.
i meant to say i knew tht stuff well...not tht i had those questions...i had d ideal gas n stuff...
stupid difficult paper.... >:(
-

same here.. i think that i can do variant 1 better than variant 2, at least according to the topics that are discussed here.
well, its luck :(
hope the threshold will be low..

Did v get to choose which variant v do at the time of registration?? Not that theres any advantage...
Cos v get to choose the 1 of 2 papers for practical :P
Our school just said v do paper 22 as it was the only 1 indicated in final O/N '09exam timetable.
So our statement of entry had paper 22
I thought there wasn't goin to b variant 1 (paper 21)! ::)
Anyways...i'm gonna b doin CIE A level chem paper 42 this wed. What bout u guys??

yea...paper 4 me too....
well after this i'm sorta worried bout tht too...
well but d funny thing is tht i know a level chem better thn as level...lol
so any ideas on what cud come??or imp topics???

oh yaa..lol :D
i had forgottn bout tht thread..lolz

stupid difficult paper.... >:(
lol.
Yeah variant 1 was easier than variant 2. :(

so i guess u had variant 2 too...lol
hmm...so i can only hope tht duznt happn again for paper4... :(
