Question

Identify the correct sentences about alkene reactions: (A) Alkenes undergo electrophilic addition, (B) Alkenes undergo nucleophilic addition in general, (C) Saytzeff's rule favors more substituted alkenes, (D) Alkenes are inert towards peracids.

• A. A, B and C only
• B. A, C and D only
• C. A, B, C and D
• D. A and C only

Hint:

Alkenes are electron-rich, so they love "Electrophiles."

Answer 1

The Correct Option is D

Step 1: Concept Alkenes are characterized by a $\pi$-bond, which acts as a nucleophile (electron-rich center).

Step 2: Meaning Their typical reactivity is defined by their interaction with electron-poor species.

Step 3: Analysis Statement A is correct; electrophilic addition is the signature reaction of alkenes. Statement B is generally incorrect as they don't easily react with nucleophiles. Statement C is correct; Saytzeff's rule states that the most substituted alkene is the major product in elimination. Statement D is incorrect; alkenes react with peracids to form epoxides.

Step 4: Conclusion Only statements A and C are factually correct. Final Answer: (D)
