Step 1
Identify the correct structural formula
Answer
To determine which option represents glycerol, we need to identify its chemical structure. Glycerol, also known as glycerin, has the structural formula C₃H₈O₃, which consists of three carbon atoms, eight hydrogen atoms, and three hydroxyl (-OH) groups.
Upon examining the provided options:
- Option A has a structure with three hydroxyl groups, which resembles glycerol.
- Option B and Option C do not represent a three-carbon structure with three hydroxyl groups.
- Option D has the same structure as option A but differently formatted, also containing three hydroxyl groups.
Upon confirming the structure, the correct answer is D.
