can u plz draw the structure............Carbon does not have enough orbital space to accomodate electrons of dative bond by chlorine!
It has no d orbital space!
i too dont get it,to explain u.. if anyone knowz plz help us...how do u get a ketone and a carbon dioxide in addition to 2 methyl propane...with hot concentrated KMNO4

wht do u mean by primary tertiary and secondary carbon?when double bond breaks , the primary carbon forms co2 , secondary forms carboxylic acid while tertiary forms ketone.. as u can see double bond is between primary n tertiary carbon the products will be co2 n ketone!
wht do u mean by primary tertiary and secondary carbon?
Candidates should be aware that allhttp://www.xtremepapers.com/papers/CIE/Cambridge International A and AS Level/Chemistry (9701)/9701_s10_qp_42.pdf
plz explain me thi question 6(d)
Man, I was gonna answer this question long time ago, but saw propane and thought that this was something new. but...phew nothing newand its 2 methyl propENE not proPANE!
Can you provide the stem of the question?Why HFCs breakdown quickly in lower atmosphere even though C-H bond is stronger than C-Cl bond?

well....it was written in the book.....so this cnfusion came into my mindCan you provide the stem of the question?
5d ii.....with HCl the basic phenylamine will immediately react to for C6H5NH3+Cl-...bt we wanted just plain old phenyl amine....dats why we add NaOHhttp://www.xtremepapers.com/papers/CIE/Cambridge International A and AS Level/Chemistry (9701)/9701_s10_qp_42.pdf
This paper is kinda tough. Does anyone know the GT for this?
Meanwhile, my questions from dis papers :
2.b) Can someone explain the calculations. Again, I've said this before, WHY is lattice enthalpy positive?!
3.d)i) dafuq?? we should find out the answers by trial and error method or what/??? also include ii) plz
5.d)ii) I don't get why we need to add NaOH at the end?!
Please help me, you're sure to get a like even for trying, I'm a likaholic
gt for this was 54! no wonder why! n yeah question 3 d is just trial n error type question!http://www.xtremepapers.com/papers/CIE/Cambridge International A and AS Level/Chemistry (9701)/9701_s10_qp_42.pdf

For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
