The HOMO-LUMO transition in the conjugation-extended1,3-butadiene molecule requires less energy than inethene. As a result:
A.1,3-butadiene absorbs light with higher frequency thanethene.
B.No change occurs in the absorption spectrum of 1,3-butadienein comparison to that of ethene.
C.1,3-butadiene absorbs light with longer wavelengths thanethene.
D.1,3-butadiene absorbs light with shorter wavelengths thanethene.
