so when they only for the organic product, it has to be RCOONA? 0.0yup thats the case just u need to balance it!
If u are asking about G2 Solubility trend: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?!
yea got it!!If u are asking about G2 Solubility trend:
it decreases down the group
due to two factors:
a)solubility inc as hydration inc as hydration gives out energy good for breaking lattic
down the group hydration decreases as G2 elements form weak water bonds! means less energy available now for lattice to break
b) Lattice Dissociation energy decreases down the group less energy required to break the lattice
but even though hydration energy decreases so much that it cant be able break the lattices
so over all it decreases down the group
i dont know whether it answered your question or not?
no i mentioned the compoundss which it can be use forso when they only for the organic product, it has to be RCOONA? 0.0
Sorry im bugging u so much! Is there any advice u cd give me for app. It doesnt get in my head! :/
okay, if u have time then a bit of explanation of NMR, analysing that graph thing with narrow mountains (not eaxctly). And yea Main points for the chromatography methods, PC, TLC, GLC, HPLC...no i mentioned the compoundss which it can be use for
also for app just go through the text book
or post it here specific issue/concept and i'll try to help!!
[Fe(H2O)6-n(NO2)n]^2+ (n=1 to 6)
How do we get that? o.o And Q2 b (iv). Q2 c (ii)[Fe(H2O)6-n(NO2)n]^2+ (n=1 to 6)
ameen, i need notes of electrophrsis, design and material? plzzz can u?get specific what u want specifically
maybe i can help !
ohhi want it too
Honestly speaking....i did that question aaaaaaages ago..so even my memory can be like that of an old woman..i dont remember :/How do we get that? o.o And Q2 b (iv). Q2 c (ii)
cuz there's a reversible sign.....and cz electrophilic addition is in alkeneshttp://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Chemistry (9701)/9701_s12_qp_41.pdf
Q3 b i) why isnt it electrophilic addition, how is it redox or redn?! :s

Q2 b(iv) either step 2 cz it involves H2 and O is formed from NO
or step 3 since it involves H2 and N2O formed from NO...
C (iii) i think u add all of them..i dunno what the heck made me erase it :/...but i can see the outlines...i've ...added them...yep Add all the three...what does the mark scheme say?
okay how exactly is it redox or redn whatever? Please please please...! :/cuz there's a reversible sign.....and cz electrophilic addition is in alkenes
type of reaction --Electrophilic addition is a mechanism plus it's reduction cz of the gain of H atoms...see that diagram? Look, both the O's have a hydrogen atom now...okay how exactly is it redox or redn whatever? Please please please...! :/
chemguide.co.ukameen, i need notes of electrophrsis, design and material? plzzz can u?
i thought so just wasnt confident...thanks a ton, Also, Q3 a, where the aryl ring is joined to that pentagon: don't we count C1-C2 as in C1 from the aryl and C2 from the penta thingy. they just counted one C atom there.:/ In some other sheet i once did this wasnt the casetype of reaction --Electrophilic addition is a mechanism plus it's reduction cz of the gain of H atoms...see that diagram? Look, both the O's have a hydrogen atom now...
