Question
Using infrared spectroscopy, how can you differentiate
between an alcohol and a carboxylic acid?
O Carboxylic acids give a strong sharp signal around 1850 cm
O Carboxylic acids give a 1H singlet around 3.8 ppm, alcohols
give a 2H singlet around 3.2 ppm
Carboxylic acids give two peaks at approximately 1700
(sharp) and 3000 (broad) cm1 while alcohols give only one
around 3500 (broad) cm 1
Alcohols give sharp medium strength signals that
correspond to hydrogens bound to an sp2
hybridized atom while carboxylic acids do not
