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

- A, B and C only
- A, C and D only
- A, B, C and D
- A and C only
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
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)
