Question

____ describes the type of molecule characterized by c-h bonds, a lack of functional groups, non - polar, and low boiling point.
○ hydrocarbons
○ carbohydrates
○ amino acids
○ lipids

Explanation:

Hydrocarbons are molecules composed of only carbon and hydrogen atoms, so they have C - H bonds, lack functional groups (since they only have C and H), are non - polar (due to similar electronegativities of C and H), and have low boiling points (especially for smaller hydrocarbons). Carbohydrates have oxygen - containing functional groups, amino acids have amino and carboxyl groups, and lipids have more complex structures with functional groups or polar regions in some cases.

Answer:

A. Hydrocarbons
