The correct Answer is:
To solve the assertion and reason question regarding acetic acid and methyl formate, we can follow these steps: ### Step 1: Understand the Assertion The assertion states that "Acetic acid and methyl formate are functional isomers." - **Definition of Functional Isomers**: Functional isomers are compounds that have the same molecular formula but different functional groups. ### Step 2: Identify the Structures Next, we need to identify the structures of acetic acid and methyl formate. - **Acetic Acid**: The structure of acetic acid (CH₃COOH) includes a carboxylic acid functional group (–COOH). - **Methyl Formate**: The structure of methyl formate (HCOOCH₃) includes an ester functional group (–COO–). ### Step 3: Compare Molecular Formulas Now, we check if they have the same molecular formula. - **Acetic Acid**: C₂H₄O₂ - **Methyl Formate**: C₂H₄O₂ Both compounds have the same molecular formula (C₂H₄O₂), confirming that they are indeed functional isomers. ### Step 4: Understand the Reason The reason states that "Functional isomers differ in the position of the carbonyl group." - **Analysis of the Reason**: While functional isomers do differ in functional groups, the statement about differing positions of the carbonyl group is not true for all functional isomers. Functional isomers can differ in functional groups entirely, not just in the position of a carbonyl group. ### Step 5: Conclusion Based on the analysis: - The assertion is **true**: Acetic acid and methyl formate are functional isomers. - The reason is **false**: Functional isomers do not necessarily differ only in the position of the carbonyl group. Thus, the correct answer is that the assertion is correct, but the reason is incorrect. ### Final Answer The correct option is (3) Assertion is correct but Reason is incorrect. ---
