In the UV-visible absorption spectrum of an α, β-unsaturated carbonyl compound, with increasing solvent polarity:
  • a)
    n-π* transition undergoes Hypsochromic shift, π-π* undergo Bathochromic shift
  • b)
    n-π* transition undergoes Bathochromic shift, π-π* undergo Hypsochromic shift
  • c)
    Both n-π*  and π-π*  transition undergoes Bathochromic shift
  • d)
    Both n-π* and π-π* transition undergoes Hypsochromic shift
Correct answer is option 'A'. Can you explain this answer?

Organic compound, the absorption peaks are due to the transition of electrons from the ground state to the excited state. These transitions occur when the energy of the incident light matches the energy difference between the ground and excited states of the molecule.

The position and intensity of the absorption peaks depend on the types and positions of the functional groups present in the molecule, as well as its conjugation system. For example, molecules containing conjugated double bonds exhibit strong absorption in the visible region, whereas those without conjugation absorb mainly in the UV region.

The UV-visible absorption spectrum can provide information on the electronic structure and bonding of the molecule, as well as its purity and concentration. It is a useful tool in many areas of chemistry, including organic synthesis, analytical chemistry, and biochemistry.

In polar solvent , excited state is more stabilised than ground state. So pi* is more stabilised than pi. So this transition takes less energy, so red shift.
But non bonding orbital is more stabilised than pi*. So this transition takes more energy , so blue shift.
