The correct Answer is:
To solve the question, we will analyze both statements provided regarding the reaction of a triester of glycerol with stearic acid when boiled with aqueous NaOH. ### Step 1: Understand the Reaction A triester of glycerol with stearic acid is known as a triglyceride. When this triglyceride is boiled with aqueous NaOH, a process called saponification occurs. This reaction produces glycerol and sodium salts of fatty acids (soap). ### Step 2: Identify the Products During the saponification of the triglyceride: - Glycerol (a syrupy liquid) is released. - Sodium stearate (the soap) is formed. ### Step 3: Evaluate Statement I **Statement I:** "A triester of glycerol with stearic acid on boiling with Aq. NaOH gives solid cake with soapy touch." - This statement is **True** because the reaction produces sodium stearate, which is a soap and can form a solid cake that feels soapy. ### Step 4: Evaluate Statement II **Statement II:** "Free glycerol is liberated which is a syrupy reaction." - This statement is **False** as it incorrectly describes glycerol as being "liberated." While glycerol is produced, it remains in a liquid state, not liberated as a solid. ### Conclusion Based on the evaluations: - **Statement I is True.** - **Statement II is False.** Thus, the correct answer is that Statement I is true, and Statement II is false. ### Final Answer The answer is: **Statement I is true, Statement II is false.** ---
