How could IR spectroscopy be used to distinguish between the following compounds? a ketone and an aldehydeAn aldehyde would show absorption bands at 2820 – 2720 cm¬1. A ketone would not have these absorption bands.O A ketone would show absorption bands at 1250 – 1050 cm-1. An aldehyde would not have these absorption bands.O A ketone would show absorption bands at 3300 – 2500 cm-1. An aldehyde would not have these absorption bands.An aldehyde would show absorption bands at 1780 – 1650 cm-1. A ketone would not have these absorption bands.SubmitRequest AnswerPart Ba cyclic ketone and an open-chain ketoneO An open-chain ketone would have a methyl substituent and therefore an absorption band at 1385 – 1365 cm¬1 that a cyclic ketone would not have.An open-chain ketone would have a methyl substituent and therefore an absorption band at 1650 – 1550 cm-1 that a cyclic ketone would not have.An open-chain ketone would have a methyl substituent and therefore an absorption band at 2960 – 2850 cm-1 that a cyclic ketone would not have.An open-chain ketone would have a methyl substituent and therefore an absorption band at 3300 – 2700 cm-1 that a cyclic ketone would not have.SubmitRequert Angwor benzene and cyclohexeneBenzene would show an sp3 C - H stretch slightly to the right of 2500 cm-1. Cyclohexene would not show an absorption band in this region.Cyclohexene would show an sp C– H stretch slightly to the right of 2500 cm-1. Benzene would not show an absorption band in this region.Benzene would show an sp3 C –H stretch slightly to the right of 3000 cm-1. Cyclohexene would not show an absorption band in this region.O Cyclohexene would show an sp3 C- H stretch slightly to the right of 3000 cm-1. Benzene would not show an absorption band in this region.SubmitRequest AnswerPart Dcis -2-hexene and trans-2-hexeneThe cis isomer would show a carbon-hydrogen bending vibration at 960 –980 cm¬1, whereas the trans isomer would show a carbon-hydrogen bending vibration at730 – 675 cm=1.The cis isomer would show a carbon-hydrogen bending vibration at 990 – 910 cm¬1, whereas the trans isomer would show a carbon-hydrogen bending vibration at890 cm-1.The cis isomer would show a carbon-hydrogen bending vibration at 730 – 675 cm-1, whereas the trans isomer would show a carbon-hydrogen bending vibration at960 – 980 cm¬1.The cis isomer would show a carbon-hydrogen bending vibration at 840 – 800 cm, whereas the trans isomer would show a carbon-hydrogen bending vibration at890 cm-1.

Question

Accepted Answer

Aldehyde and ketone both have different absorption bands and thus showing different IR Spectrum.…
