Question:
The IUPAC name of the compound \(HOCH_2(CH_2)_3CH_2COCH_3\) is
The IUPAC name of the compound \(HOCH_2(CH_2)_3CH_2COCH_3\) is
Show Hint
When both -OH and -CO- are present, the suffix "-one" takes priority over "-ol" for numbering.

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
IUPAC naming: Select the longest carbon chain containing the principal functional group (ketone here). Number to give the principal group the lowest number.
Step 2: Detailed Explanation:
Structure: HO-CH\(_2\)-CH\(_2\)-CH\(_2\)-CH\(_2\)-CH\(_2\)-CO-CH\(_3\).
Total carbons: 7 (heptane). Principal group: ketone (one at C2). Hydroxy group (-OH) at C7.
Numbering from the end closer to the ketone: CH\(_3\)-CO- is C1-C2? No — ketone gets lower number: CO is at C2, so CH\(_3\) is C1. Then chain extends to OH at C7.
Name: 7-Hydroxyheptan-2-one.
Step 3: Final Answer:
The IUPAC name is 7-Hydroxyheptan-2-one.
