The steps involved in the mechanism of formation of cyclic acetal from acetone and ethylene glycol in the presence of anhydrous HCl are to be shown. Concept introduction: The reaction of a ketone or an aldehyde with an excess of diol (single compound with two hydroxyl groups) under acidic conditions results in the formation of cyclic acetal.

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.
