Which of the following comparison is correct for solvent shift on the n –>π* transition of acetone?
Which of the following comparison is correct for solvent shift on the n –>π* transition of acetone? Correct Answer H20 < CH30H < C2H50H < CHC13 < C6H14
H-bonding with ground state in n–> π* results in increase in energy gap & decrease in wavelength. And as polar solvents show strong H-bonding. So, the correct option is H20 < CH30H < C2H50H < CHC13 < C6H14.
