Options are:
-- hydrocarbon bonds.
-- complex carbohydrates.
-- nuclei chains.
-- carbon chains.
Given those answer options, answer the question: Answer the following question given this paragraph: Amines are capable of hydrogen bonding though their boiling points are generally a bit lower than the corresponding alcohol. Methylamine and ethylamine are gases at room temperature, while larger amines are liquids. As with other organic compounds that form hydrogen bonds, water solubility is reflected in the length of the carbon chains. Smaller amines are soluble, while larger ones are less soluble. Q: As with other organic compounds that form hydrogen bonds, water solubility of amines is reflected in the length of what? A:
A:
carbon chains
