Question

Which of the following conditions lead to formation of ozone?

• A. When oxygen molecules absorb ultraviolet photons and undergo photolysis
• B. When carbon molecules absorb ultraviolet photons and undergo photolysis
• C. When oxygen molecules absorb ultraviolet electrons and undergo photolysis
• D. When oxygen molecules absorb ultraviolet neutrons and undergo photolysis

Answer 1

The correct option is A When oxygen molecules absorb ultraviolet photons and undergo photolysis

When oxygen molecules absorb ultraviolet photons and undergo photolysis, ozone is obtained
$3O_2\underset{photolysis}{\overset{UVlight}{\to }}2O_3$.
