Current Question (ID: 17866)

Question:

$\text{Photochemical smog formed in congested metropolitan cities mainly consists of:}$

Options:

1. $\text{Ozone, SO}_2, \text{ and hydrocarbons.}$
2. $\text{Ozone, PAN, and NO}_2$
3. $\text{PAN, smoke and SO}_2$
4. $\text{Hydrocarbons, SO}_2, \text{ and CO}_2$

Solution:

$\text{HINT: PAN, ozone and NO}_2 \text{ are main components of photochemical smog.}$ $\text{STEP 1: Photochemical smog is a type of smog produced when ultraviolet light from the sun reacts with nitrogen oxides in the atmosphere.}$ $\text{It is visible as a brown haze, and is most prominent during the morning and afternoon, especially in densely populated, warm cities.}$ $\text{STEP 2: The major undesirable components of photochemical smog are nitrogen dioxide (NO}_2\text{), ozone (O}_3\text{), PAN (peroxyacetyl nitrate), and chemical compounds that contain the –CHO group (aldehydes).}$ $\text{PAN and aldehydes can cause eye irritation and plant damage if their concentrations are sufficiently high.}$
