What is the correct IUPAC name for the compound with the structure ?
A
Butane
B
Pentane
C
Hexane
D
Propane
Verified step by step guidance1
Identify the number of carbon atoms in the longest continuous chain of the compound. Count each carbon atom connected in a straight line without branching.
Write down the alkane name corresponding to the number of carbons in the longest chain. Use the prefix for the number of carbons followed by the suffix '-ane' for alkanes.
For 3 carbons, the name is 'propane'; for 4 carbons, 'butane'; for 5 carbons, 'pentane'; and for 6 carbons, 'hexane'.
Since the compound structure is CH\_3-CH\_2-CH\_2-CH\_2-CH\_3, count the carbons: there are 5 carbons in a straight chain.
Therefore, the correct IUPAC name corresponds to the alkane with 5 carbons, which is 'pentane'.
