D
2-Methylpropane
Verified step by step guidance
1
Identify the carbon chain in the given structure: The molecule is shown as CH\_3-CH\_2-CH\_2-CH\_3, which is a continuous chain of four carbon atoms connected by single bonds.
Determine the longest continuous carbon chain: Since there are four carbons in a row without any branches, the longest chain is four carbons long.
Recall the IUPAC naming convention for alkanes: The base name depends on the number of carbons in the longest chain. For four carbons, the base name is 'butane'.
Check for any substituents or branches: The given structure has no branches or substituents attached to the main chain, so no prefixes or numbers are needed.
Conclude the IUPAC name: Since the molecule is a straight-chain alkane with four carbons and no branches, the correct IUPAC name is 'butane'.
