The boxes below are labeled by ranges within the infrared
spectrum, representing the wavelengths at which specific functional
groups absorb energy. The scale is shown in wavenumbers, cm–1.
Classify each functional group according to the approximate range
where it would produce a stretch on the spectrum. Note: The
stretches of the functional groups may not fill the entire
range.

The functional groups in an organic compound can frequently be deduced from its infrared absorption spectrum. A compound, C3H.O2, exhibits intense absorption at 1740 em1 accompanied by a band at 1050 cm-1. No absorption above 3000 cm-1 is present Relative absorption intensity: (s)-strong, (m)-medium, (w)-weak. What functional class(es) does the compound belong to? List only classes for which evidence is given here. Attach no significance to evidence not cited explicitly. Do not over-interpret exact absorption band positions. None of your...
