whatever man. can't be bothered to convince you that hsc has nothing to do with understanding... vast knowledge would be the knowlegde of the hsc syllabus like knowing haber was a poison squad leader in the german army or something.

here is the thread where the dude posted at if you haven't read it: http://www.boredofstudies.org/community/showthread.php?s=&threadid=20665&perpage=15&pagenumber=21

He got third. I think he wrote the right stuff.

i apologise, i have an inclination to enter into an arguement to defend my case

 

[Xayma]

Actually I stuffed up the ozone thing, each atoms doesnt have a single covalent bond to each other. What happens is you effectively get two 1 1/2 bonds between the two outer atoms towards the center atom.

LOL. here is a pic.

Yeah I know, but Ill draw a better one in a sec. SO I dont know why they are disjointed, something to find out.

 

[Xayma]

Ok heres a better one I quickly did in paint (the electrons are a little off though).

Oh yeah and the double arrow is a resonance arrow which indicates that it is actually a hybrid fo the two forms.

 

[Wohzazz]

the two ozone look the same to me except flipped
all I know is ozone has 2 double covalent bond and 1 coordinate covalent bond..i think the reason why is has the coordinate bond is because of the order of reaction. O3 is produced from O2 and O so the addition of O to a stable O2 results in a coordinate bond in O3. O3 is thus made more unstable because of the bond. Right reasoning?

 

[Wohzazz]

Also, Xayma do you do accelerated class or something or do you just know your HSC stuff?

what the? ok i'll draw a stupid freehand one fast.

i thought the 2 electron of the middle O is suppose to be together according to Xayma
damn you people can utilise your paint and scanner properly

it doesn't matter... i don't even have a scanner... its called paint with mouse.

as if you'll know where the hell the electron will be at. its just showing the bonds. but its conventional to even out the remaining electrons ie put them both sides.

 

[Xayma]

Ok ozone doesn't have a double bond and doesn't have a single bond, it has two 1 1/2 bonds, in the same way that benzene doesnt have double bonds and single bonds

Not accelerated at all. I know a fair bit of chem and physics before we learn it in class buts thats because I do alot of reading of sciency books.

 

[Wohzazz]

What is a half bond?

you'll get hammered if you do that in hsc.

Wow, if i had that much motivation, i wouldn't have to spend my chrissy holidays reading the text books. So ozone doesn't have the two electrons together?

 

[Xayma]

It isnt really a half-bond but the negativity of that electron is shared over the whole molecule.

 

[abdooooo!!!]

im telling you people if you do write ozone has two 1 1/2 bonds because of phenomena of resonance, you'll get fucked to the maximum. i found that out...

edit: stop complicating and learning the actual right way... just learn the hsc way. dammit.

 

[Constip8edSkunk]

ozone has a resonating coordinate bond meaning that that third pair is effectively shared by all 3 O atoms so both diagrams are correct...

edit: whoa... like 8 posts appeared from when i was reading the thread lol
