Question

1,3-Pentadiene and 1,4-pentadiene are compared with respect to their intrinsic stability and reaction with $\text{HI}$ . The correct statement is

• A. 1,3-pentadiene is more stable and more reactive than 1,4-pentadiene
• B. 1,3-pentadiene is less stable and less reactive than 1,4-pentadiene
• C. 1,3-pentadiene is more stable but less reactive than 1,4-pentadiene
• D. 1,3-pentadiene is less stable but more reactive than 1,4-pentadiene

Answer 1

Answer: (A)

As conjugated alkenes are more stable and more reactive due to effective resonance so 1,3-pentadiene is more stable and more reactive than 1,4-pentadiene
