We’re on Bondi Beach to discuss the ozone layer – a topic of great interest to Australians. More chemistry at www.periodicvideos.com Follow us on Facebook at www.facebook.com And on Twitter at twitter.com

@donghanyao Rarely? do I laugh hard enough to cry, especially for a YouTube comment
@PainSurgeon Thanks. I never took college chemistry.?
@otleybey Thanks, that’s? kind of what I figured. If this resonance is measurable, then it cannot be denied.
@L00NGB00W The ring strain involved would make it unfavourable. Also, ozone has resonance stabilisation which? would be lost in a 3-membered ring.
@L00NGB00W Ozone cannot form a? ring. It’s a rookie mistake on exams in the first year of college. Ozone is a resonance structure from O = O – O to O – O = O. The central atom is sp² hybridized. The angle in this molecule is about 117° . The Lewis structure could suggest a ring is possible, but don’t be fooled by it. If you somehow manage to squeeze ozone in the right angle, a ringlike structure would be unlikely or dissappear almost instantly.
@otleybey True. Perhaps I should have said a series molecule instead of linear…
?
A ring should be possible based on valence electrons. Three oxygen atoms could form three co-valent bonds. But the geometry might not work. =/
@L00NGB00W It’s not linear. Ozone is bent. I don’t think it is possible for a ring to exist, but? the quantum mechanics is probably quite complicated.
I always assumed that ozone was a ring shaped molecule like benzene. But it turns out it’s? a linear molecule as per the professor’s model. Probably why it’s so unstable…
I wonder if it’s possible for an O³ allotrope to exist in a ring under the right conditions?
I found it? really hard to focus on this lecture, especially @6:50… for some reason…
4:15?
Let’s turn the chlorine back into the? Earth… LOL hahaha…
@frichikendz I think we should squirt them? with aeresols.
min 4:15? the best
I thought the crystals that caused ozone depletion in the upper atmosphere were actually? CO2 crystals, but the prof seems to know what he’s talking about.
on an unrelated note:
6:17
…:)
Nice specs? Prof!
I don’t think I’ve ever? seen anyone look as cool as Professor Poliakoff in this video.
look? who’s talking about hairspray.
When they? panned to the surfer and other people, my attention was lost, and I couldn’t follow what he was saying any more.
he’ll get a tan if not? careful
6:49 hot? chicks
omg? i learn more chemistry on this than my high school teacher taught me for a year…
Around 6:40 the prof flickers? when he said “disappear”.
I thought he was off back to the mothership
Those? shades are the ultimate chick magnet.
How exactly will the CF3Cl be? washed away in the atmosphere?
At 4:15 could the prof see the reflection on? the inside of his glasses?
