Place these dienophiles in order of least to most reactive with a common diene : 1,1,2-trichloroethene , 1-cholorethene , 1,1,2,2-tetrachloroethene , 1,2-dicholorethene
Accepted Answer
The order of reactivity of these dienophiles with a common diene from least to most reactive is:
1. 1,1,2,2-tetrachloroethene (least reactive)
2. 1,1,2-trichloroethene
3. 1,2-dichloroethene
4. 1-chloroethene (most reactive)
This order is determined by the electron-withdrawing effect of chlorine atoms. More chlorine atoms on the alkene lead to a more electron-deficient dienophile, making it less reactive in a Diels-Alder reaction.
