a)
Interpretation:
The molecules given are to be arranged from shortest to longest wavelength on the basis their wavelength of maximum absorption in UV spectroscopy.
Concept introduction:
Extended conjugation shifts the UV absorption maxima to higher wavelengths. For example, the UV absorption maxima for 1,3-butadiene is 217 nm and that of 1,3,5-hexatriene is 258nm.
