Consider the Following Molecules

question 20

Multiple Choice

Consider the following molecules. What is the relationship between the degree to which the molecule is oxidized and its polarity?

• A)The greater the degree of oxidation, the more polar the molecule. Therefore, acetic acid is both the most oxidized and the most polar.
• B)The greater the degree of oxidation, the less polar the molecule. Therefore, ethane is both the most oxidized and the least polar.
• C)Only acetaldehyde and acetic acid are oxidized and polar because they contain a double-bonded carbon-oxygen bond, C=O. Of the two, acetaldehyde is more polar.
• D)There is no correlation between degree to which a molecule is oxidized and its polarity.

Definitions:

Non-electrolytes

Substances that do not produce ions when dissolved in water, and hence do not conduct electricity in solution.

Non-electrolyte

A substance that does not readily ionize when dissolved or melted and is therefore a poor conductor of electricity.

Dissociate

In chemistry, it refers to the process by which molecules, ions, or complexes split into smaller particles or ions, often reversible and influenced by environmental conditions.

Aqueous Solution

A mixture where water acts as the dissolving medium.
