Q.
Diels-Alder reaction will not take place with which of the following reactants?
EAMCETEAMCET 2010
Solution:
In Diels-Alder reaction, conjugated dienes react with enes or olefinic compounds and give cycloalkenes.
Since, (buta-1,4-diene) is not a conjugated alkene, it will not take part in Diels-Alder's reaction.
