Which of the following reactants and conditions would result in maximum formation of methyl propanoate?
a. propanol, methanoic acid, HCl, heat
b. ethanol, propanoic acid, HCl, heat
c. methanol, propanal, conc. HCl, heat
d. methanol, propanoic acid, heat
e. methanol, propanoic acid, HCl, heat
Homework Answers
Answer = e (methanol, propanoic acid, HCl, heat)
CH3OH + CH3CH2COOH ---------> CH3CH2COOCH3 +H2O
An ester is formed when alcohol is warmed with a carboxylic acid, this reaction is known as esterification.
In this HCl is used as the acid catalyst. The option e will yield the maximum formation of methyl propanoate.
