Question

The secondary precursors of photochemical smog are-SO-2- and NO-2-NO-2- and hydrocarbonsCO-2- and O-2-O-3- and hydrocarbons

Toppr Admin · Accepted Answer

Photo chemical smog occurs in warm and dry climate by the action of sunlight on the oxides of nitrogen- NO2 and O3 are strong oxidizing agents- They react with unburnt hydrocarbons to produce formaldehyde- acrolein- and PAN-xA0- i-e peroxyacetyl nitrate- These are the secondary compounds of photochemical smog-

	List - I		List - II
