    Here's what I get

    Explanation:

    There are two methods of naming esters.

    (a) Common names

    alkyl alcohol + carboxylic acid ⟶ alkyl carboxylate

    To form the name of an ester, you drop the alcohol and - ic acid ending from the names of the reactants.

    The name of the ester consists of two words: the name of the alcohol followed by the acid name with the ending - ate.

    (b) IUPAC (systematic) names

    alkanol + alkanoic acid ⟶ alkyl alkanoate

    To form the name of an ester, you drop the - anol and - ic acid endings from the names of the reactants.

    The name of the ester consists of two words with the corresponding endings - yl and - ate.

    You don't mix the common and IUPAC systems in the same name.

    1. ethanol + benzoic acid ⟶ ethyl benzoate

    2. benzyl alcohol + acetic acid ⟶ benzyl acetate

    3. butanol + butanoic acid ⟶ butyl butanoate (IUPAC)

    butyl alcohol + butyric acid ⟶ butyl butyrate (common)

    4. pentanol + propanoic acid ⟶ pentyl propanoate (IUPAC)

    n-pentyl alcohol + propionic acid ⟶ n-pentyl propionate (common)

    5. isopropyl alcohol + formic acid ⟶ isopropyl formate
