Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
IUPAC nomenclature rules:
The longest chain containing the functional group is selected.
Numbering is done so that the functional group gets the lowest number.
The suffix “-ol” is used for alcohols.
Step 2: Detailed Explanation:
The given compound CH$_3$CH$_2$CH$_2$OH has three carbon atoms in a straight chain. The hydroxyl (-OH) group is attached to the first carbon, so its correct name is 1-propanol.
Step 3: Final Answer:
The IUPAC name of CH$_3$CH$_2$CH$_2$OH is 1-propanol.
