1,3-Butadiene, the Simplest Conjugated Diene, Has a UV Absorption at 217

Question 24

Essay

1,3-Butadiene, the simplest conjugated diene, has a UV absorption at 217 nm. (One nanometer = 10-9 meter.)
a. Calculate the energy of UV radiation with this wavelength (in kJ mol-1). Show your work.
b. Shown is an MO electron-occupancy diagram for the molecular orbitals of 1,3-butadiene. Draw an arrow on this diagram that corresponds to the energy of this UV radiation.
