Question

Under basic conditions, compound II will form a conjugate system while compound I will not. Give a possible explanation and provide the mechanism that shows the formation of the conjugated system in compound II.

Accepted Answer

Compound II will form a conjugated system because it contains an α-hydrogen, while compound I does not.The mechanism for the formation of the conjugated system for Compound II:

Answer

Compound I will not form a conjugated system due to the presence of α-hydrogens.The mechanism for the formation of the conjugated system for Compound II:

Answer

Compound II will form a conjugated system because it already has a conjugated system present.The mechanism for the formation of the conjugated system for Compound II:
