Chemistry Applications

[Jazib]

I want help in the following topics:
DNA finger printing
X-Ray crystallography
quantom dots.
(a summarised explanation wud b great. thnx)

 

[Zazzyo]

Whats quantum dots :O ? its in chemistry?

 

[princesszahra]

ill do em tonight and let u know tomorrow!

 

[Vnza]

X-Ray crystallography might not come as it came in the recent papers. i think in n09.

 

[Jazib]

lol. yeah quantom dots are in applications.
n thnx in advance zahra
leaving the topic just becuz it came in last paper aint a wise thing to do, not for me atleast :/

 

[Vnza]

No i know. It can come. Btw Jazib what you said about Green Chemistry i heard Sir Warraich said the same about those 12 points.

 

[Jazib]

lol yeah SIr Waraich made all those predictions
n remembring that his prediction in AS did came, i will get these topics done fo sure!
btw, i got his evening classes in LLC. what about u?

 

[mdaniyal]

Quantum dots is really ajeeeb type ki cheez!!!plz tell!!!! and kya X ray crystallography detail main a sakti hai i mean calculations or Xray diffractometer???????????????????? :shock:

 

[Jazib]

quantom dots, i need help too.
n X ray crystalography, my teacher told dat it wont come in detal.
but it is mentioned in sylabus. so, i m not feeling comfortable not knowing it!

 

[princesszahra]

ya i went through those topics
its better u guys ask ur questions abt the topic
!! i understood it!

 

[Vnza]

Nae i dint take any tuitions. Any p2 predictions? Sir Shahbaz teaches us at school. He can just teach organic chem.

 

[Anomaly]

NMR and the last bit of applications is though, quantum dots are only briefly discussed (didnt understand them completely though :S

 

[Zazzyo]

... my teacher havent tuahgt quantum dots.. wa is it abt?.. ill check in app buklet right nw :l

 

[Jazib]

ahh sory about p2, already cleared it last year in AS. but sir warraich did gave predictions about p4. btw ur school is?
n yeah guys, quantom dots come under the nanochemistry. i did got some of it, but since my teacher told us straight that he doesnt knw about em, so its not cleared...

 

[Jazib]

ya i went through those topics
its better u guys ask ur questions abt the topic
!! i understood it!

Xray crystalography. how do u determine the structure of a compound using that technique?

 

[princesszahra]

not to be formal
its like where there r electrons u get a shadow i mean like u get an X ray
but this one is sharp and with good contrast
so u cant get to know where electrons r present!
any more questions/??

 

[Jazib]

oh k... thnx.
havnt got em yet, i'll bring em wen i've solved past papers....

 

[princesszahra]

oht oki !!!
