Question

Which one of the following choices describes most accurately the actual, internal reaction
temperature (in other words, the temperature of the reaction mixture inside the reaction vial)
for the Fischer esterification experiment of 1-butanol with acetic acid to form n-butyl acetate? Select one, and explain your answer.
a) Sand bath temperature (160-180 °C)
b) Boiling point of 1-butanol (116-118 °C)
c) Boiling point of the reaction mixture (reflux temperature)
d) Boiling point of acetic acid (117 °C)
e) Boiling point of n-butyl acetate (124-126 °C)

Explanation / Answer

Option c) Boiling point of the reaction mixture is correct

Reaction originally occurs at this temperature, because at this temperature both the reactants are in gaseous mixture. For remaing temperatures one of reactant or both the reactnats are boiled off.
