Current Question (ID: 17867)

Question:

$\text{The aromatic compound that is present as particulate among the following is:}$

Options:

1. $\text{Benzene}$
2. $\text{Toluene}$
3. $\text{Nitrobenzene}$
4. $\text{Polycyclic hydrocarbons}$

Solution:

$\text{HINT: PAHs are present as particulates.}$ $\text{Explanation:}$ $\text{Polycyclic aromatic hydrocarbons (PAHs) are a group of organic compounds consisting of two or more fused aromatic rings.}$ $\text{PAHs originate mainly from anthropogenic processes, particularly from incomplete combustion of organic fuels. PAHs are distributed widely in the atmosphere.}$ $\text{Natural processes, such as volcanic eruptions and forest fires, also contribute to an ambient existence of PAHs.}$ $\text{PAHs can be present in both particulate and gaseous phases, depending upon their volatility.}$
