B) (II), (III), (IV)
C) (III), (IV)
D) (II)
Correct Answer: C
Solution :
[c](I) For Diels-Alder reaction, dienes should have EDG and dienophile should have EWG. So (I) does not react. |
(II) Diene (buta-l,3-diene) has S-trans conformation, so does not react. |
(III) Undergoes Diels-Alder reaction. |
(IV) Undergoes intramolecular Diels-Alder reaction. |
