Which of the following is the correct IUPAC name for the compound with the molecular formula C4H10?
A
Hexane
B
Pentane
C
Propane
D
Butane
Verified step by step guidance1
Identify the molecular formula given in the problem, which is C4H10.
Determine the number of carbon atoms in the compound. The molecular formula C4H10 indicates there are 4 carbon atoms.
Recall the IUPAC naming convention for alkanes, which is based on the number of carbon atoms: 1 carbon is 'meth-', 2 carbons is 'eth-', 3 carbons is 'prop-', 4 carbons is 'but-', and so on.
Since the compound has 4 carbon atoms, the prefix 'but-' is used, and since it is an alkane (saturated hydrocarbon), the suffix '-ane' is added.
Combine the prefix and suffix to form the IUPAC name: 'butane'.
