Nitric oxide (NO) is the nucleus of photochemical smog.
2NO(g) + `O_(2) ("air") rarr 2NO_(2)` (g)
`NO_(2)(g) overset("Sunlight")(rarr) `NO(g) + [O]
[O]`+ O_(2) (g) rarr O_(3)(g)`
Both `NO_(2) and O_(3)` are strong oxidising agents and react with unburnt hydrocarbons in the polluted air to produce formaldehyde, acrolein and peroxyacetyl nitrate (PAN). These products are harmful to the plant and animal life. Catalytic converters are now installed in the automobiles to reduce the photochemical smog. Photochemical smog can also be supressed by certain compounds, which act as free radical trap.
Which are the primary constituents of photochemical smog ?

A

`So_(2) and CO`

B

`NO_(2)` and hydrocarbons

C

`CO_(2) and NO_(2)`

D

Hydrocarbons and CFCs
