yes! .. lol ... http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Chemistry (9701)/9701_w12_qp_41.pdfU knw its better if some things in ms r ignored! Btwn i heard ms r made aftr we give xam! Btwn i agree wid the website!! Until the alkli is mention it is not justified to write Na u c!! BOL 4 xam!
yup yup Exactly, feel prety shy to collidefor the last one, it's slow cause they both r anions ...that's a right reason too eh?
May Allah bless u mate!! evn if u dnt ask me, I do remember everyone in my prayers... Jazak Allah Khair! btw any tips for app?
Cheerio!
MashAllah !!Can some body please explain me ph ksp pka ka kc kw stuff
Really need help
Also what about the titration curves we draw for them, i mean do we plot it at the given volume? Or what
It decreases down the group!!yes! did ma'am vani tell u abt that ms thingy?! jk ;P.. lol ... http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Chemistry (9701)/9701_w12_qp_41.pdf
Hey sis just wanna clear one thing 2 e) what happens to the LE and HYD and Soln...cause answer in my notes and ms r diff! for LE thingy.
BOL too!
lol dont say sorrySorry to disturb you again but one thing more for the same Q3)e) why is benzene reacting with excess Br(aq) if any catalyst of FeBr2 isnt present ?
knowitall10 if u know plzz help me with this
no no bahi its not ChI3 which is attatchedJazak Allah khair! is that CI3? but the MS says something else? So it's necessary for a coupling reacn to have alkaline soln?!
Thanks a ton. Stay blessed!
well i was thinking the same but in ms hums are without those productsOne more thing. http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Chemistry (9701)/9701_w12_qp_41.pdf
Q3 b) do we have to mention NO+1/2O2 in the middle of the two mountains?
everytime it has to b that eqn? what if it's CH3CO instead of C6H5OH, then it'd be CH3COONA? is it?!no no bahi its not ChI3 which is attatched
ChI3 is the side product giving yellow ppt
the products are:
NaI3 + h20 + ChI3 + (C6H5Oh)-COONa+
its TriIodo methane test:
u warm the X Compound with NaOh and I2
X compound can only be following
a) Ethanol
b) all secondry alcohols
c) only aldehyde ethanal
d) all methyl ketones
hope this helps!
Pray for me please
i want it tooanyone plz give me chem application notes plzzz??
god help those who help others
if hydration dominates then it'd soluble?! and i was talking abt the lattice energy? it increases down the grp as the ionic character increases cause the polarising ability decreases! I never learnt what u just stated...Or maybe i can't comprehend it? I'm sorry. Elaborate if u can?!It decreases down the group!!
LD(lattice dissociation) decreases down the group (good for solubility)
hyd(hyd) dec down the group(bond length inc) bad for solubility
hydration factors dominates the Lattice dissociation factor hence solubility decreases down the group!!
yup yup Exactly, feel prety shy to collide
Tips: study Environmental chemistry, Analytical Chemistry and Design and Material
yup thats the case just u need to balance it!everytime it has to b that eqn? what if it's CH3CO instead of C6H5OH, then it'd be CH3COONA? is it?!
Jazak Allah Khair. And no worries, deffo will pray for u! You too remember me in ur prayers.
get specific what u want specificallyanyone plz give me chem application notes plzzz??
god help those who help others
so when they only for the organic product, it has to be RCOONA? 0.0yup thats the case just u need to balance it!
