Answer:\u00a0<\/strong>The difference between esterification and saponification reactions of organic compounds is that esterification is a chemical reaction in which a carboxylic acid (organic acid) reacts with an alcohol (organic compound) to form an ester (organic compound) and water. On the other hand, saponification is a reaction in which an ester reacts with a strong base (like NaOH) to produce a carboxylate salt (soap) and an alcohol.<\/p>\n\n\n\n

Complete Answer:<\/strong><\/p>\n\n\n\n

Esterification and saponification are two important organic reactions involving esters, but they occur in opposite directions and have different reactants, products, and applications. The table below clearly explains the differences between them:<\/p>\n\n\n\n

Saponification is a chemical reaction used to make soaps. Soaps are the sodium or potassium salts of fatty acids, like sodium stearate (C\u2081\u2087H\u2083\u2085COONa<\/strong>). Fatty acids are carboxylic acids (R\u2013COOH) with long, straight carbon chains. These chains can be saturated or unsaturated, and usually have an even number of carbon atoms (4 to 28).<\/p>\n\n\n\n

In saponification, an ester of a fatty acid (R\u2013COOR’<\/strong>) reacts with a strong base like NaOH (sodium hydroxide). This breaks the ester and forms a carboxylate salt (soap) and an alcohol (R’\u2013OH). For example:<\/p>\n\n\n\n

C\u2081\u2087H\u2083\u2085COOCH\u2083 + NaOH \u2192 C\u2081\u2087H\u2083\u2085COONa + CH\u2083OH<\/strong>
(Methyl stearate + Sodium hydroxide \u2192 Sodium stearate (soap) + Methanol)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Even though a carboxylic acid (R\u2013COOH) is formed first, it quickly reacts with the base to form a salt (R\u2013COONa) and does not stay in its acid form.<\/p>\n\n\n\n
