WebSince C-H bonds don't hydrogen bond very well, you don't see that phenomenon in an ether, and an O-H peak is very easy to distinguish in the IR spectrum. Problem IR5.1. Even though there are only two C-O bonds in dibutyl ether, the C-O stretching mode is even stronger than the peak at 2900 cm-1 arising from 10 different C-H bonds. Explain why. WebThis is a very useful tool for interpreting IR spectra: Only alkenes and aromatics show a C–H stretch slightly higher than 3000 cm -1. Compounds that do not have a C=C bond show C–H stretches only below 3000 cm -1. Aromatic hydrocarbons show absorptions in the regions 1600-1585 cm -1 and 1500-1400 cm -1 due to carbon-carbon stretching ...

Esters have a memorable pattern of three intense peaks at ~1700, ~1200, and ~1100 from the C=O and two C-O stretches, and hence follow what I call the Rule of Three (7). An example of the spectrum of a saturated …
