how was the chemistry unit 2 paper?

[U stalking ME]

Results? *Sigh

Results on 23rd August, thats wat i heard

For the ammonia question, I wrote that since it's pungent it would repel animals and unwanted people from the car. for the reason why ozone is better than chlorine I wrote that Ozone can be freely found in the atmosphere, while chlorine has to be synthised, and for the reason why they used ammonia and fuel, I wrote that the fuel is used to burn the ammonia

no offense but lol wat will we do if we smell ammonia run for our lives?

what i mean is you can know if there is any leakage..

okay no offense man

What was the shape of the intermediate Y? And explain!

its trigonal planar i think i messed that question up *sigh* every QWC was awful

 

[schoolation]

I think trigonal planar is right!
I did it * Tetrahedral because of repulsion between 3 bonding pairs and 1 very stable carbocation surrounded by bulky groups. They repel for maximum separation* after the exam I recognised that it was absolutely wrong

well we tried our best lets finish the rest of the papers and then pray to Allah

yep let's do that...

btw I just have one last little thing the ppm question was 47 right?

i dont even remember lol

i got 47.5, what about O18 isotope? it wrote it's a catalyst and equilibrium was reached sooner

I dont remember the value, But for 18 O i wrote it is a catalyst so doesnt affect equilibrium position.

keeping my fingers crossed that we all get good grades!

 

[yousef0074]

was the product of elimination 2-methylpropene?

 

[Romani2011]

was the product of elimination 2-methylpropene?

Got the same answer

 

[xIshtar]

I dont remember the value, But for 18 O i wrote it is a catalyst so doesnt affect equilibrium position.

I wrote that as it was added, it provided drive for the equilibrium and thus it was used to create more ozone so that dynamic equilibrium could be reached again

 

[shruthi.s]

yay i got that too! for the mole calculation qn, did you guys get these really small answers? like 2.something x 10^(-5) :O

 

[U stalking ME]

I wrote that as it was added, it provided drive for the equilibrium and thus it was used to create more ozone so that dynamic equilibrium could be reached again

But didnt it say there was no affect on equilibrium on addition of 18O

 

[xIshtar]

Yeah I guess it did, but I couldn't think of anything else
