What is the correct IUPAC name for the compound with the structure ?
A
Pentane
B
Methane
C
Propane
D
Butane
Verified step by step guidance1
Identify the number of carbon atoms in the longest continuous chain of the compound. The given 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 prefix indicates the number of carbons: 'meth-' for 1, 'eth-' for 2, 'prop-' for 3, 'but-' for 4, and 'pent-' for 5 carbons.
Since the compound has 4 carbons, the correct prefix is 'but-'. The suffix '-ane' is used for alkanes, which are saturated hydrocarbons with only single bonds.
Combine the prefix and suffix to form the name: 'but' + 'ane' = 'butane'.
Verify that there are no branches or functional groups that would change the name. Since the structure is a straight chain alkane with 4 carbons, the correct IUPAC name is 'butane'.
