D. More chemically reactive

Question 17.

Sources of pollutants

1. High temperature combustion

2. Pulp and paper industry

3. Pesticides

4. Sour gas plants

Match each source of pollutant as numbered above with its pollutant as listed below. Use each number only once

17. Dioxins/furans

18. SO2(g)

19. Nox(g)

20. Phosphates

c). 2-iodopropane

14) C). Fluoroethene

16) D). More chemically reactive

17) 1). High temperature combustion  - Dioxins/furans

2). Pulp and paper industry  - SO2(g)

3). Pesticides  - Phosphates

4). Sour gas plants - Nox(g)

Explanation:

The correct name for molecule I would be '2-iodopropane' where the number 2 reflects the position of iodine. There are three carbons and 8 hydrogen atoms which reflect that it is an alkane compound. In the given carbon chain. In this chain of three carbons, iodine is present on the second carbon. Therefore, option C is the correct answer.

14). The appropriate name for molecule III exemplifies Fluoroethene as it consists of two carbons due to which it belongs to the 'ethane' group and it bears the prefix 'fluoro as it belongs to fluorine group and the suffix '-ene' due to double bond.

16). Synthetic hydrocarbons are 'more chemically reactive' and therefore, it generates greenhouse gases and leads to climate change, global warming, depletion of the ozone layer, etc.

17). 1). Dioxins are generated as a result of high-temperature combustion processes like commercial waste incineration or burning of fuels.

2). Pulp and paper industry releases various gases like nitrogen oxide, sulfur dioxide SO2(g), carbon dioxide, etc.

3). Phosphate is the pollutant released from pesticides that badly affects the fertility of the soil.

4). Nox(g) nitrogen oxide released by sour gas plants and coal-fired emissions is a major contributor to increased greenhouses gases and global warming.
