A)methanol and propionic acid
B)ethanol and propionic acid
C)propanol and propanoic acid
D)1-propanol and ethanoic acid
E)2-propanol and ethanoic acid

Propyl ethanoate is an ester with the formula CH3COOCH2CH2CH3. It can be formed by the reaction between propanol (CH3CH2CH2OH) and ethanoic acid (CH3COOH). Hence, the correct choice is D. Methanol and ethanol cannot be used to form propyl ethanoate, as they have only one carbon atom in their structures. Propanol and propanoic acid cannot be used to form propyl ethanoate, as they have three carbon atoms each, and the resulting ester would have six carbon atoms total. 2-propanol and ethanoic acid cannot be used to form propyl ethanoate, as 2-propanol (also known as isopropyl alcohol) has a branched structure, and the carbon chain in propyl ethanoate is straight.
