Which consequence results when increased sigma bond delocalization forms in butadiene?

A)Increased ultraviolet light absorption
B)Reduced chemical reactivity overall
C)Enhanced structural rigidity notably
D)Decreased torsional bond stiffness

💡 Explanation

Increased conjugation in butadiene lowers the energy gap between the HOMO and LUMO due to *molecular orbital theory*, because the electrons are spread across multiple carbon atoms; therefore, ultraviolet absorption increases, rather than reduced reactivity because of this delocalisation.
