What is the IUPAC name of glycerol?

Correct option is D

The correct answer is: (D) Propane-1, 2, 3-triol

The IUPAC name of glycerol is Propan-1, 2, 3-triol. It is a simple three-carbon alcohol with hydroxyl groups (-OH) attached to each of the three carbon atoms. The name reflects the structure of the molecule, where:

• "Propan" refers to the three carbon atoms.
• "1, 2, 3" indicates that the hydroxyl groups are attached to each of the three carbons.
• "Triol" means it has three alcohol (OH) groups.

Additional Knowledge: :

• Ethane-1, 2-diol: This name corresponds to ethylene glycol (C₂H₆O₂), not glycerol.
•  2-Methylpropan-1-ol: This name corresponds to isobutanol (C₄H₁₀O), not glycerol.
• Propan-1-ol: This is the IUPAC name for propanol (a 3-carbon alcohol with one -OH group attached at the 1st carbon), not glycerol.
