Which of the following represents saponification reaction? 

(a) CH_3COONa + NaOH \overset{CaO}{\rightarrow} CH_4 + Na_2CO_3 

(b) CH_3COOH + C_2H_5OH \overset{H_2SO_{4}}{\rightarrow}CH_3 COOC_2H_5 + H_2O

(c) 2CH_3COOH + 2Na \rightarrow 2CH_3COONa + H_2

(d) CH_3COOC_2H_5 + NaOH \rightarrow CH_3 COONa + C_2H_5OH

 

Answers (1)

Answer: (d)

Solution:

When an ester is heated with sodium hydroxide solution, ester gets hydrolyzed (breaks down) to form the parent alcohol and sodium salt of carboxylic acid. This process is called as saponification. Equation (d) has alcohol and sodium salt of carboxylic acid.

Therefore, option (d) is correct.
