Q. A powerful eye irritant in the smoke is
Peroxyacetyl nitrate is a peroxyacetyl nitrate. It is a secondary pollutant present in photochemical smog. It is thermally unstable and decomposes into peroxyethanoyl radicals and nitrogen dioxide gas. It is a lachrymatory substance.
- Ozone
- Sulphur dioxide
- Carbon dioxide
- Peroxyacetyle nitrate
Answer: Peroxyacetyl nitrate
Peroxyacetyl nitrate (PAN) is primarily responsible for the eye irritation so characteristic of this type of smog.
smog is made from smoke +fog so how it answer for eye irritant in eye..sulphur dioxide is also eye irritant
ReplyDeletePeroxyacetyl nitrate (PAN; CH3C(O)OONO2) is an important constituent of photochemical smog. It is also a ubiquitous chemical present throughout the global troposphere. A unique property of PAN is that it is very stable at cold temperatures and easily decomposes to release NOx at warm temperatures. In remote atmospheres, it can act as a carrier and a reservoir of NOx, which is necessary for ozone (O3) formation. Peroxyacyl nitrates (PANs) are known to be eye irritants (lachrymators), phytotoxins, and bacterial mutagens. The most serious biological effects of PANs are of a phytotoxic nature resulting in injury to plants and vegetation.
