The stretching absorption bands are to be labeled in the given figure: alkene or aromatic C-H stretches at ∼ 3050 cm -1 , alkane C-H stretches between 2800 and 3000 cm -1 , a C=O stretches at ∼ 169 0 cm -1 and a C=C stretches at ∼ 165 0 cm -1 . Concept introduction: IR spectroscopy enables to identify different functional groups in the molecule. One of the greatest advantages of IR spectroscopy is that the frequency of a particular type of vibration is typically found within a characteristic range of frequencies, regardless of the functional group with which the vibration is associated. The fact that absorptions by certain vibrations appear with characteristic frequency ranges enables us to use IR spectroscopy to obtain structural information about a molecule.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
