Understand the IUPAC naming conventions: IUPAC names are systematic names that describe the structure of a compound, while common names are traditional names that may not reflect the structure accurately.
Analyze each pair: Compare the IUPAC name with the common name provided to determine if they describe the same compound.
Examine 'butanoic acid: acetic acid': Butanoic acid is a four-carbon carboxylic acid, while acetic acid is a two-carbon carboxylic acid. These names do not match the same compound.
Examine 'ethene: acetylene': Ethene is a two-carbon alkene (C2H4), while acetylene is a two-carbon alkyne (C2H2). These names do not match the same compound.
Examine 'methanol: methyl alcohol': Methanol is a one-carbon alcohol (CH3OH), and methyl alcohol is another name for methanol. These names match the same compound.
