The position for the absorption band for carbonyl stretching vibration (frequency = 5.1 x1013 vibrations /second) is a) 1700 cm-1 b) 1000 cm-1 c) 3000 cm-1 d) 2500 cm-1

Correct order of carbonyl stretching frequency is(1 Ponto)acetone > formaldehyde >ethanoyl chloride > acetaldehydeethanoyl chloride> formaldehyde > acetaldehyde > acetoneacetone < formaldehyde < ethanoyl chloride < acetaldehydeethanoylchloride< formaldehyde < acetaldehyde < acetone

The energy transition (expressed in terms of vibrational energy levels) that gives rise to the absorbance at 1600 cm-1 is likely to be:
