All the steps involved in the acid-catalyzed formation of a cyclic acetal from ethylene glycol and an aldehyde or ketone are to be shown. Concept introduction: Aldehydes and ketones react with alcohols in the presence of acids to yield hydroxyethers called hemiacetals. In the presence of acids the hemiacetal reacts with another alcohol molecule to yield acetals. If the second alcoholic group is present in the same molecule, like in glycols, a cyclic acetal will result. To show: All the steps involved in the acid-catalyzed formation of a cyclic acetal from ethylene glycol and an aldehyde or ketone.

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.
