Chemistry 9701/P22

[moonlight93fgs]

the kc was 0.44 (0.4)(0.4)/(0.6)(0.6)

functional group in lastr quest was ester

chiral centres were 2

other abundant gas was co2

two useful properties of cfc's were they are easily compressible, they are non toxic, they r not flammable....


any other questions plz ask


there were only 14 marks for organic in paper 2 so mayebe there will be more organic mcq's so be prepared friends :wink: :wink:

vat was da structural formula of trans isomer in da organic ques.?...

 

[zahraahmed]

for trans isomer simply draw different groups on both sides of the double bond

 

[princesszahra]

good luck with the results!!

 

[Talha]

but they said for a structural formula... so i didnt drew!!

 

[BILALrox01]

no.....CO2 is correct for the formation of BACO3....but in the other part they asked about an aqueous reagent used for the formation of BASO4.....so for that I am asking why is SO2 not a correct reagaent?.....

So2 will react to givw barium sulfite not sulfate

 

[Heeebooo]

I don't know which language do you people understand!
I've told you people a jillion times ( and many other good members did, too). But all in vain!
I request you again to discuss the paper after ONLY 24 hours!
