Question

What is the IUPAC name of the following compound ?

• A. Phenyl butane
• B. 3-Hexyl hexane
• C. 3-Hexyl butane
• D. 2-Phenyl butane

Hint:

When naming an organic compound, identify the longest carbon chain and the position of substituents (like phenyl groups), and number the chain accordingly.

Answer 1

The Correct Option is D

The given compound has a phenyl group attached to a butane chain at the second carbon position. The structure of the compound is: \[ \text{CH}_3-\text{C}(\text{C}_6\text{H}_5)-\text{CH}_2-\text{CH}_3 \] This structure corresponds to the IUPAC name 2-Phenyl butane, as the phenyl group is attached to the second carbon of the butane chain.
