Given the following structure: , what is the correct IUPAC name for this compound?
A
Propane
B
Pentane
C
D
Butane
Verified step by step guidance
1
Identify the number of carbon atoms in the given structure. The structure is CH\_3-CH\_2-CH\_2-CH\_3, which contains 4 carbon atoms connected in a straight chain.
Recall the IUPAC naming rules for alkanes: the name is based on the longest continuous carbon chain, and the suffix '-ane' indicates all single bonds (alkane).
Since there are 4 carbons in a straight chain with only single bonds, the base name corresponds to 'butane' (where 'but-' means 4 carbons and '-ane' means single bonds).
Check the other options: 'propane' has 3 carbons, 'pentane' has 5 carbons, and '2-butene' indicates a double bond at carbon 2, which is not present here.
Conclude that the correct IUPAC name for the compound CH\_3-CH\_2-CH\_2-CH\_3 is 'butane'.
