Consider the Following Molecules

question 124

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.
