JEE Mains · Chemistry · STD 11 - 9. Hydricarbon
Following are the four molecules "P", "Q", "R" and "S".
Which one among the four molecules will react with \(\mathrm{H}-\mathrm{Br}_{(\mathrm{aq})}\) at the fastest rate?
- A R
- B P
- C Q
- D S
Answer & Solution
Correct Answer
(C) Q
Step-by-step Solution
Detailed explanation
Addition of \(\mathrm{H}-\mathrm{Br}_{(\mathrm{aq})}\) to alkene follows electrophilic addition mechanism. In the rate determining step a carbocation intermediate is formed. Among P, Q, R & S compound Q will form most stable carbocation intermediate since it is resonance…
