The correct Answer is:
To analyze the given question, let's break it down step by step: ### Step 1: Understand the Assertion The assertion states that "Alkynes are less reactive than alkenes towards electrophilic reagents." - **Explanation**: This is true because alkynes (which contain a carbon-carbon triple bond) have their pi electrons held more tightly compared to alkenes (which contain a carbon-carbon double bond). The tighter hold on the pi electrons in alkynes makes them less reactive towards electrophilic addition reactions. ### Step 2: Understand the Reason The reason provided is "The general formula of alkenes is CnH2n-2." - **Explanation**: This statement is incorrect. The correct general formula for alkenes is CnH2n, where 'n' is the number of carbon atoms. For example, when n=2, the alkene is C2H4 (ethene), not CnH2n-2. ### Step 3: Evaluate the Relationship Between Assertion and Reason - Since the assertion is correct and the reason is incorrect, we can conclude that the reason does not explain the assertion. ### Conclusion Based on the analysis: - The assertion is correct. - The reason is incorrect. - Therefore, the correct option is **c. Assertion is CORRECT but Reason is INCORRECT.** ---
