Show the catalysis of the breakdown of ozone by radical X
X· + O3 → XO· + O2
XO· + O → X· + O2
Overall : O3 + O → 2O2
Write the equations of the radical substitution of C5H12 with Br2
- Initiation
* Br–Br –> Br· + Br· - Propagation
* C5H12 + Br· –> ·C5H11 + HBr·
* ·C5H11 + Br2 –> C5H11Br + Br· - Termination
* Br· + Br· –> Br2
* ·C5H11 + Br· –> C5H11Br
* ·C5H11 + ·C5H11 –> C10H22
Overall
C5H12 + Br2 –> C5H11Br + HBr
