Which one of the following statements regarding photochemical smog is not correct?

(1) Photochemical smog is formed through

photochemical reaction involving solar energy

(2) Photochemical smog does not cause irritation in eyes and throat.

(3) Carbon monoxide does not play any role in photochemical smog formation

(4) Photochemical smog is an oxidising agent in character

$\mathfrak\green{Answer}$

$\bigstar$ (2) Photochemical smog does not cause irritation in eyes and throat.

$\mathfrak\red{Reason}$

Photochemical smog is the chemical reaction of sunlight, nitrogen oxides and volatile organic compounds in the atmosphere, which leaves airborne particles and ground-level ozone.

Being an irritant of the eyes, nose, throat and lungs, ozone is known to particularly affect asthmatics and people with respiratory problems.

The primary route of exposure to nitrogen oxides is by inhalation, but exposure by any route can cause systemic effects. Nitrogen oxides are irritating to the eyes, skin, nose, mucous membranes and respiratory tract.
