It should be d
Answer 2

There are two characteristics of molecules, one is geometry and other is shape. Shape is excluding lone pair surrounding the central element and geometry is including the lone pair. Therefore, the correct option is option D.

What is VSEPR theory?

VSEPR stands for valence shell electron pair repulsions. VSEPR theory is used to predict the shape and geometry of molecules on the basis of valence electrons pairs that are present around the central element of the molecule.

According to VSEPR theory, Lone pair lone pair repulsion is greater than bond pair bond pair repulsion. There are so many limitations of VSEPR theory. There is a repulsion between bond pair electrons and lone pairs present on the central element.  The shape of a molecule affect how the molecule is involved with living systems as it determines how the molecule functions.

Therefore, the correct option is option D.

Answers

Answer:

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.
