Identify to which type does the following complex reactions belongs to- saponification of a diester in presence of an alkali

The process of making soap by the hydrolysis of fats and oils with alkalies is called saponification. In this, oils and fats are heated with a solution of sodium hydroxide to form sodium salt of the respective fatty acids. Therefore, it involves multiple substrate in the chemical reaction. Therefore, it is a sequential reaction. R ' OOC CH 2 n COOR → NaOH R ' OOC CH 2 n COOH → NaOH HOOC CH 2 n COOH
