Chapter 24: Problem 52

Write a balanced chemical equation using condensed structural formulas for (a) the formation of butyl propionate from the appropriate acid and alcohol, (b) the saponification (base hydrolysis) of methyl benzoate.

Short Answer

Expert verified
(1) Formation of butyl propionate: CH3CH2COOH + CH3CH2CH2CH2OH → CH3CH2COOCH2CH2CH2CH3 + H2O (2) Saponification of methyl benzoate: C6H5COOCH3 + NaOH → C6H5COONa + CH3OH

Step by step solution

01

(1) Formation of butyl propionate

Butyl propionate can be formed by the esterification reaction between propanoic acid and butanol. We will first write the condensed structural formulas for both reactants and then the product and write a balanced chemical equation for the reaction. Propanoic acid condensed structural formula: CH3CH2COOH Butanol condensed structural formula: CH3CH2CH2CH2OH Butyl propionate condensed structural formula: CH3CH2COOCH2CH2CH2CH3 The balanced chemical equation for the formation of butyl propionate: CH3CH2COOH + CH3CH2CH2CH2OH → CH3CH2COOCH2CH2CH2CH3 + H2O
02

(2) Saponification of methyl benzoate

To write the saponification (base hydrolysis) reaction of methyl benzoate, we will first write the condensed structural formulas for methanol benzoate and the base (sodium hydroxide), and then the products of the saponification reaction. Methyl benzoate condensed structural formula: C6H5COOCH3 Sodium hydroxide condensed structural formula: NaOH Products of the saponification reaction: - Benzoic acid condensed structural formula: C6H5COOH - Methanol condensed structural formula: CH3OH - Sodium ions: Na+ The balanced chemical equation for the saponification of methyl benzoate: C6H5COOCH3 + NaOH → C6H5COONa + CH3OH
