What is the IUPAC name for the compound with the structure ?
A
Pentane
B
Butane
C
Methane
D
Propane
Verified step by step guidance1
Identify the molecular formula of the given compound by counting the number of carbon atoms in the longest continuous chain. The structure given is CH\_3-CH\_2-CH\_2-CH\_3, which has 4 carbon atoms connected in a row.
Recall the IUPAC nomenclature for alkanes, which are hydrocarbons with only single bonds. The names are based on the number of carbons: 1 carbon is methane, 2 is ethane, 3 is propane, 4 is butane, and 5 is pentane.
Since the longest chain has 4 carbon atoms, the base name of the compound will be 'butane'.
Check for any branches or substituents attached to the main chain. In this case, the structure is a straight chain with no branches, so no additional prefixes or numbers are needed.
Conclude that the correct IUPAC name for the compound CH\_3-CH\_2-CH\_2-CH\_3 is 'butane'.
