Cwhat's the answer?
N-N bond breaks as it is very weak (energy 160 Kj/mol). NF2 is the single product. Statement 1 is incorrect. Statement 2 is correct as 160 is the energy of the bond that breaks. Molecules non linear as a lone pair present on N of NF2
Solve for each equation.View attachment 62435

Go to the data booklet, there you'll find 4. Standard Electrode potential ................................, there you'll find the equation for oxidation of Sn2+ to Sn4+ and reduction of KMNO4, just balance them so that the mole ratio of electrons is the same on both sides and then add the two equations, the electrons will cancel out to give you the equation, and then you know the rest!
Thanks bro!Thanks!
March 2017 P1 for you all
Yo are very welcome, anytimeAppreciations and a thunderous Applause for you.
Thank you teacher.

can you plz be more clearSolve for each equation.
I will only show for D, which is the right answer.
Initial moles of P = 2 mol
mol at equilibrium of R = x
so for equation D,
mol at equilibrium of P = 2 - x
mol at equilibrium of Q = x/2
Sum of all mol at equilibrium expressions
x+(2-x)+(x/2)
Simplifies to [2+(x/2)] which should be the total moles according to the question.
could you plz explain why you left out the fifth carbon?
A.
Why is 3 correct?
I can't see the right side of the question, should I assume that the charge is -3?

For papers from 2013 and 2012, I have created some videos to explain the MCQs. You can search through the playlists
June 2013, Paper 11What paper is this??
Variant???
A- Inital: 2 : 0 : 0can you plz be more clear
Q22) C-Br bond longest and weakest (Br atomic radius largest) so C-Br bond will be the first to undergo homolytic fission.M2017 p12 Q 22 anyone? http://papers.gceguide.com/A Levels/Chemistry (9701)/9701_m17_qp_12.pdf
Ans A can anyone explain why isnt it the other options??
Q26 Why isnt it A? doesnt Kmno4 oxidise secondary alcohol to ketone??
Q27 ??????????

HELP!!
Q22) C-Br bond longest and weakest (Br atomic radius largest) so C-Br bond will be the first to undergo homolytic fission.
Q26) You said it yourself, "ketone"... The product shown in A is not ketone, but an aldehyde. Ketone would be CH3COCH3.
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.
