Help me out please. Esterification and equations. ?

Question

Write balanced equations for esterification reactions involving each of the following.

A. propanoic anhydride and ethanol

B. benzoic acid and 1-propanol

C. 2,3-dichlorobutanoic acid and 2,2-dimethyl-3-pentanol

Answer 1

A. Structural equation:

CH3CH2(C=O)O(O=C)CH2CH3 + CH3CH2OH → CH3CH2CO2CH2CH3 + CH3CH2CO2H

Or, in terms of molecular formulas:

C6H10O3 + C2H6O → C5H10O2 + C3H6O2

B. Structural equation (C6H5 is a benzene ring):

C6H5CO2H + CH3CH2CH2OH → C6H5CO2CH2CH2CH3 + H2O

Molecular formula version:

C7H6O2 + C3H8O → C10H12O2 + H2O

C. Structural equation:

CH3CHClCHClCO2H + CH3CH2CH2C(CH3)2CH2OH → CH3CHClCHClCO2CH2C(CH3)2CH2CH2CH3 + H2O

Molecular formula version:

C4H6O2Cl2 + C7H16O → C11H20O2Cl2 + H2O
