Which of these reactions is not a part of breakdown of ozone in stratosphere?

1. • O Cl 2 ⎯⎯→ ClO 2 (g) + • l C (g)
2. • O Cl (g) + O(g) ⎯⎯→ Cl(g) + O 2 (g)
3. ) g ( O ) g ( l C 3 + • ⎯⎯→ • O Cl (g) + O 2 (g)
4. CF 2 Cl 2 (g) ⎯→ ⎯ uv l C • (g) + 2 F C • Cl(g)

Correct answer: • O Cl 2 ⎯⎯→ ClO 2 (g) + • l C (g)
