Among the following, the incorrect statement is
1 chlorofluorocarbons are responsible for ozone layer depletion
2 greenhouse effect is responsible for global warming
3 ozone layer does not permit infrared radiation from the sun to reach the earth
4 acid rains are mostly because of oxides of nitrogen and sulphur
Explanation:
Ozone layer does not permit UV radiations from the sun to reach the earth.

Assertion : The electronic structure of \(\mathrm{O}_{3}\) is Reason : structure is not allowed because octet around O cannot be expanded
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Ozone is considered to be a resonance hybrid of the following two forms. Octet expansion is not possible in oxygen as it does not have vacant \(d\) orbitals. Therefore, option (1) is correct.

When a slow dry steam of oxygen is passed through a silent electric discharge, conversion of oxygen to ozone (10%) occurs. The product is
1 Ozonised oxygen
2 Diatomic oxygen
3 Both (1) and (2)
4 Neither (1) nor (2)
Explanation:
When a slow dry stream of oxygen is passed through a silent discharge, conversion of oxygen to ozone \((10 \%)\) occurs. The product is known as ozonised oxygen.
