Question

Quizplus · Accepted Answer

The most energetically favorable UV transition for 1,3-butadiene is the π to π* transition, which involves the promotion of an electron from a bonding π orbital to an antibonding π* orbital. This transition is typically lower in energy compared to n to π* or σ to σ* transitions.
