Question

The correct IUPAC nomenclature of the following compound is:

• A. Propyl-2-bromo-6-methyl heptanoate
• B. 2-Bromo-5-methyl-1-propyl heptanoate
• C. Propyl-2-bromo-5-ethyl hexanoate
• D. Propyl-2-bromo-5-methyl heptanoate

Hint:

When naming a compound, identify the longest carbon chain as the parent, number the chain to give the lowest locants for substituents, and apply standard naming conventions for functional groups and halogens.

Answer 1

The Correct Option is D

Step 1: Analyze the structure.
In the given compound, the longest chain is a heptane chain, and the ester functional group is at the end. The bromo group is at position 2, and the methyl group is at position 5. Step 2: Apply IUPAC naming rules.
- The parent chain is heptane. - The ester group is on the 1st carbon. - The bromo group is attached to the second carbon. - The methyl group is attached to the fifth carbon. Step 3: Conclusion.
The correct IUPAC name is "Propyl-2-bromo-5-methyl heptanoate." Final Answer: \[ \boxed{\text{Propyl-2-bromo-5-methyl heptanoate}}. \]
