Question

How could you spectroscopically tell the difference between 1-propanol and 1-propene

they have different masses, so mass spectrometry could be used

-OH group should be clearly visible in their IR spectrum

C=C double bond should be easily identified from their IR spectra

all of the above

they have different masses, so mass spectrometry could be used

-OH group should be clearly visible in their IR spectrum

C=C double bond should be easily identified from their IR spectra

all of the above

option D is correct

Explanation:

Mass spectroscopy is used to idenstified as they have different masses.

-OH group gives a stretch at 3300-3600 cm-1 whereas alkene C=C is identified at 3010-3100 am-1.
