Vedclass · Answer

(B) Classical smog is a mixture of smoke,fog,and sulfur dioxide $(SO_2)$,which acts as a reducing agent. Hence,it is called reducing smog.Photochemical smog is formed by the action of sunlight on nitrogen oxides $(NO_x)$ and hydrocarbons. Its common components include ozone $(O_3)$,nitric oxide $(NO)$,acrolein,formaldehyde $(HCHO)$,and peroxyacetyl nitrate $(PAN)$.Classical smog components are primarily $SO_2$ and particulate matter,not $O_3, NO, HCHO$. Therefore,the statement in option $B$ is incorrect.

List-$I$	List-$II$
$(A)$ $< 1 \ ppm$	$(i)$ Harmful to bones
$(B)$ $> 2 \ ppm$	$(ii)$ Tooth decay
$(C)$ $> 10 \ ppm$	$(iii)$ Brown mottling of teeth

Column-$I$	Column-$II$
$(A)$ Acid rain	$(1)$ $CHCl_2-CHF_2$
$(B)$ Photochemical smog	$(2)$ $CO$
$(C)$ Combination with hemoglobin	$(3)$ $CO_2$
$(D)$ Depletion of ozone layer	$(4)$ $SO_2$
	$(5)$ Unsaturated hydrocarbons
