D

Verified step by step guidance
1
Identify the number of carbon atoms in the longest continuous chain of the given compound. The structure is CH\_3-CH\_2-CH\_2-CH\_3, which contains 4 carbon atoms in a row.
Recall the IUPAC naming convention for alkanes, where the name is based on the number of carbon atoms: 1 carbon = Methane, 2 carbons = Ethane, 3 carbons = Propane, 4 carbons = Butane, 5 carbons = Pentane, and so on.
Since the compound has 4 carbon atoms and no branches or functional groups, it is a straight-chain alkane.
Therefore, the correct IUPAC name corresponds to the alkane with 4 carbons, which is Butane.
Verify that the structure matches the name by ensuring all carbons are single-bonded (alkane) and the molecular formula fits C\_4H\_10.
