Answer:
See explanation and image attached.
Explanation:
A free radical reaction is a reaction that involves species having an odd number of electrons.
The initiation step involves the formation of the odd electron species. The propagation steps produce more odd electron species while the termination steps eliminate the odd electron species.
The halogenation of alkanes occurs by free radical mechanism. The initiation, propagation and termination steps for the free radical chlorination of cyclohexane and cyclobutane is shown in the image attached.

Answer:
They include: Chemical nature of the pollutant - how active and toxic it is to humans, plants and animals; Concentration - the amount of the chemical per unit volume of air, water, soil, and; Persistence or longevity - how long the pollutant remains in the environment in its harmful form.
Explanation:
Air pollutants like ozone, particulate matter, carbon monoxide, nitrogen oxide, sulfur dioxide, lead cause atmospheric pollution which regards to ozone depletion, GH effect, climate change and human health effects. If anyone say the main factors of air pollution beyond of industry, means of transportation, solid waste generation and urbanization.
Growing urbanization and industrialization grows more pollution. Due to a large number of population in the world, more pollution is generated. Specifically if we talk about air pollution, due to steady increase in number of industries, the gradient level is deteriorating day by day. There is no good if we just talk about sustainable development if we are not following it.
