⚡ Enter ArenaIf a carbonyl compound lacks symmetry, which spectroscopic transition becomes more probable?
A)Microwave rotational transitions
B)UV-Vis electronic transitions
C)Raman vibrational transitions
D)Infrared vibrational transitions✓
💡 Explanation
Asymmetric carbonyls exhibit a larger change in dipole moment during vibration; therefore, infrared vibrational transitions become more probable due to the selection rule requiring a change in dipole, rather than solely depending on polarizability changes needed for Raman activity.
