Question

a) which band is due to the C=O absorption?

b) is this bond also present in ketones?

c) what bond do the signals at ~2750 and ~2850 cm-1 likely correspond to in aldehydes? Explain

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.
