30919 Green house gases can be arranged in 'Global Warming Potential' sequence as

1

N_{2} O > C F C > C H_{4} > C O_{2}

2

C F C > N_{2} O > C H_{4} > C O_{2}

3

C F C > C O_{2} > N_{2} O > C H_{4}

4

C O_{2} > C F C > N_{2} O > C H_{4}

Explanation:

$C F C > N_{2} O > C H_{4} > C O_{2}$

1

C F_{2} C l_{2} (g) \overset{h v}{\to} \overset{\cdot}{C l} (g) + \overset{\cdot}{C} F_{2} C l (g)

2

C l \overset{\cdot}{O} (g) + O (g) \to \overset{\cdot}{C l} (g) + O_{2} (g)

3

C H_{4} + 2 O_{3} \to 3 C H_{2} = O + 3 H_{2} O

4

H O C l (g) \overset{h v}{\to} \overset{\cdot}{O} H (g) + \overset{\cdot}{C} l (g)

Explanation:

$C H_{4}$ is not present in stratosphere.

Environmental Chemistry

30921 The upper stratosphere consisting of the ozone layer protects us from the sun’s radiation that falls in the wavelength region of

1

200 - 315 n m

2

400 - 550 n m

3

0.8 - 1.5 n m

4

600 - 750 n m

Explanation:

In ozone layer the wavelength of $U . V$ radiation is $200 - 340 n m .$
