Choose the wrong set of molecular formulas – IUPAC name – common name from the following options. A. C4H9OH – Butanol – butyl alcohol B. CH3OH – Methanol – Methyl Alcohol C. C3H8OH – Propanol – Propyl Alcohol D. C2H5OH – Ethanol – Ethyl Alcohol

C4H9OH - Butanol - butyl alcohol
CH3OH - Methanol - Methyl Alcohol
C3H8OH - Propanol - Propyl Alcohol
C2H5OH - Ethanol - Ethyl Alcohol

The correct answer is C. C3H8OH – Propanol – Propyl Alcohol.

The molecular formula of propyl alcohol is C3H7OH. The IUPAC name of propyl alcohol is propan-1-ol. The common name of propyl alcohol is propyl alcohol.

The molecular formula of butanol is C4H9OH. The IUPAC name of butanol is butan-1-ol. The common name of butanol is butyl alcohol.

The molecular formula of methanol is CH3OH. The IUPAC name of methanol is methanol. The common name of methanol is methyl alcohol.

The molecular formula of ethanol is C2H5OH. The IUPAC name of ethanol is ethanol. The common name of ethanol is ethyl alcohol.

Therefore, the wrong set of molecular formulas – IUPAC name – common name is C3H8OH – Propanol – Propyl Alcohol.
