Question

What is the IUPAC name of isopropyl alcohol?

• A. Propanol-2
• B. Propanone-2
• C. Propanal-2
• D. None of these

Hint:

When naming alcohols in the IUPAC system, use the correct placement of the hydroxyl group (-OH) on the carbon chain and ensure proper numbering.

Answer 1

The Correct Option is D

The IUPAC name of isopropyl alcohol is propan-2-ol, not "propanol-2" as stated in the options. The correct way to name alcohols is by following the IUPAC system, where the position of the hydroxyl group (-OH) is indicated by the number before the "-ol" suffix, and the alkane root is modified accordingly. Therefore, the correct IUPAC name is propan-2-ol.
