Question

____ describes the type of molecule characterized by c-h bonds, either an aldehyde or ketone, and multiple hydroxyl groups and are typically polar.
○ carbohydrates
○ amino acids
○ hydrocarbons
○ lipids

Explanation:

To solve this, we analyze each option:

• Carbohydrates: Molecules with C - H bonds, aldehyde/ketone groups, multiple hydroxyl groups, and are polar. This matches the description.
• Amino Acids: Contain amino and carboxyl groups, not matching the given structure.
• Hydrocarbons: Consist of only C and H, no hydroxyl or carbonyl (aldehyde/ketone) groups as described.
• Lipids: Generally non - polar, and their structure doesn't fit the given description.

Answer:

A. Carbohydrates
