No you are right. I should structure. Thanks.Mostly correct stuff but the setting out should be improved on. The question starts by asking about the differences in structure so that's what you should begin with.
Oxygen is a non-polar molecule with a linear structure, with one double O=O covalent bond.
Ozone is a polar molecule which gives it its bent structure. It contains a coordinate covalent bond (O=O-O you should draw the molecules).
Then it asks for two differences in their properties:
Ozone's higher molar mass (3 Oxygen molecules instead of 2), means it has increased dispersion forces acting on it which gives it higher boiling and melting points than Oxygen.
Since Ozone is polar, it also has strong dipole-dipole forces between molecules , which makes it more soluble in water (also a polar molecule) than oxygen which is non-polar.
Other properties you could include:
Ozone is more reactive and is a stronger oxidising agent, which is due to its unstable structure.
Ozone is more easily decomposed than oxygen which is very stable. This is also due to ozone's unstable structure.
Hope this helps
Someone please correct me if I made any mistakes.

The beauty of doing 4u maths, 2 other units are english leaving you with 4 more units (2 subjects).
All i have left is bio, chem and math exams hahahah

I wish I did 10 units with 4u maths, my lyf would have been so much better.
Good luck with the rest of your exams!

oooA combination question which tests on the integration of knowledge across different modules
What do you think the question would focus on?
what about vapour?
what about bromine?
Yes the cyclohexene, cyclohexane and bromine water solution are all toxic if they were to be inhaled and may cause irritation/burns when coming in contact with the skin.
On top of that some fume cupboards are fitted so that there is no natural light as the presence of U.V. Light will constitute a substitution reaction
