Answer the following question given this paragraph: Aldehydes and ketones can work weak hydrogen bonds with water through the carbonyl oxygen atom. The lower members of both series (3 carbons or fewer) are soluble in water in all proportions. As the length of the carbon chain increases, water solubility decreases. Similar to ethers, neither aldehydes nor ketones can hydrogen bond with themselves. As a result, their boiling points are generally lower than those of alcohols. Unlike alkanes however, aldehydes and ketones are polar molecules due to the more electronegative oxygen atom. The dipole-dipole interactions are stronger than the dispersion forces present in alkanes. The boiling points of aldehydes and ketones are intermediate between those of alkanes and alcohols. For example, the boiling point of ethane is -89C, ethanal is 20C, and ethanol is 78C. Q: Aldehydes and ketones can work weak hydrogen bonds with water through what atom? Choices: - basalt oxygen atom - pyridinium oxygen atom - carbon carbon atom - carbonyl oxygen atom A:
A:
carbonyl oxygen atom
