What is the IUPAC name for a straight-chain alkane containing ten carbons?

• A. Hexane
• B. Decane
• C. Octane
• D. Nonane

Answer: (B)

The IUPAC name for a straight-chain alkane containing ten carbons is Decane. The naming of alkanes follows a systematic approach based on the number of carbon atoms present in the longest continuous chain. Each alkane has a specific prefix that corresponds to its number of carbon atoms. For a straight-chain alkane, the prefix for ten carbon atoms is "dec-" which is derived from the Greek word for ten. Thus, the full name is "Decane." In contrast, hexane, octane, and nonane refer to straight-chain alkanes with six, eight, and nine carbon atoms, respectively. Therefore, these options do not accurately represent a compound with ten carbon atoms. Understanding these prefixes is crucial for accurately naming alkanes and reinforces the systematic nature of organic nomenclature.
