The gas 'A' is having very low reactivity reaches to stratosphere. It is non-toxic and non-flammable but dissociated by UV-radiations in stratosphere. The intermediates formed initially from the gas 'A' are :

A

`overset(*)CH_3 + overset(*)Cl + overset(*)CF_2 Cl`

B

`Cloverset(*)O + overset(*)CF_2 Cl`

C

`Cloverset(*)O + overset(*)CH_3`

D

`Cloverset(*)O + overset(*)CGF_2 Cl`

Text Solution

Verified by Experts

The correct Answer is:
B
In stratosphere CFCs get broken down by powerful UV radiations releasing `Cl^*` ·
`CF_2 Cl_2 (g) overset(U.V)to Cl^* (g) + ""^*CF_2 Cl(g)`

Stratosphere contains a stable layer of ozone molecules which absorbs UV radiation from the sun. The presence of ozone in atmosphere serves, as a shield to protect living organism on earth from the harmful effects of the solar ultraviolet radiation. The ultraviolet radiation are known to cause skin cancer. Ozone is formed in stratosphere by the following photochemical reactions. O_(2)(g)overset(UV)rarrO(g)+O(g) O(g)+O_(2)(g)overset(UV)hArrO_(3)(g) Ozone is thormodhynamically unstable and ecomposes to molecular oxygen. Thus a dynamic equilibrium exits between the production and decomposition of ozone molecules. Earth is protected from UV radiation by

The gas A is used by most of the animals to obtain energy from food by the process of respiration. When A is acted upon by radiation X, it gets converted into another gas B which is an allotrope of A but poisonous when inhaled. B forms a kind of layer C in the upper atmosphere which absorbs radiations X coming from a source Y and prevent them from reaching the earth. Some chemicals Z released from the various devices on the earth are destroying the layer C slowly. In fact, a hole has already been formed in layer C over the aea D of the earth. (a) What are gases (i) A, and (ii) B? Write their molecular formulae. (b) Name the layer C. (c) What are (i) X, (ii) Y, (iii) Z ? (d) Name the area D. (e) Name any two human ailments which may be caused by X.

Given below are two statements : Statement I : Chlorofluoro carbons breakdown by radiation in the visible energy region and release chlorine gas in the atmosphere which then reacts with stratospheric ozone. Statement II : Atmospheric ozone reacts with nitric oxide to give nitrogen and oxygen gases, which add to the atmosphere.
