Photochemical smog consist of excessive amount of \(x\) in addition to aldehyde, ketone, \(PAN\) etc. \(X\) is
1 Methane
2 Carbon mono oxide
3 Carbondioxide
4 Ozone
Explanation:
Photochemical smog is basically a mixture of bad chemicals. It consist of nitrogen oxides, ozone, volatile organic compounds and \(PAN\). It is caused by air pollution.

Taj Mahal is threated by pollution form
1 Sulphur dioxide
2 Hydrogen sulphide
3 Chlorine
4 Carbon dioxide
Explanation:
The reaction of sulphur dioxide with water molecules present in atmosphere forms sulphuric acid which gets precipitated through acid rain, This precipitation can cause decolouring, cracks and decomposition of the monument. The location of Mathura Refinery near to the Taj Mahal is a major reason for the accumulation of the sulphur dioxide in the rain. Hydrogen and oxygen are the natural components of water. Chlorine does not contribute to the acid rain. Hence, the correct answer is 'sulphur dioxide:
