Question

The brown haze of photochemical smog is largely attributable to: (A) NO (B) NO2 (C)  (D) CH2 = CHCH=O

Tardigrade Admin · Accepted Answer

Photochemical smog is initiated by the photochemical dissociation of NO 2 that result in the formation of NO. This NO rapidly reacts with O 3 to give NO 2 (brown gas), responsible for causing haze if its concentration is very high. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/04fd7c3e9cb48c2ef5a9136f9e62ef52-.png" />

Q. The brown haze of photochemical smog is largely attributable to:

$NO$

$N O_{2}$

$C H_{2} = C H C H = O$

Photochemical smog is initiated by the photochemical dissociation of $N O_{2}$ that result in the formation of NO. This NO rapidly reacts with $O_{3}$ to give $N O_{2}$ (brown gas), responsible for causing haze if its concentration is very high.
