Ozone - Structure, Bond energies and the Hole

Presentation for the teaching of the structure of ozone using Lewis structures to highlight resonance and discuss delocalisation. Covers the connection between bond strength and wavelength of ultraviolet light required for bond dissociation in both oxygen and ozone molecules. Finally discusses ozone layer and effect of CFCs and nitrogen oxides including key equations to show catalytic nature. Designed for IB higher level bonding topic. Fully scaffolded worksheet allows students to take detailed notes of lesson. Also features a number of previous past paper questions from its original location in the environmental chemistry option and a suitable video to consolidate learning.
