A stepwise mechanism for the given reaction is to be drawn. Concept introduction: Acetals are the groups in which carbon atom is bonded with two OR groups through single bonds. They are used as protecting groups for aldehydes and ketones as they are stable enough in neutral to strong basic condition.However, they are unstable in acidic media, and dissociates into corresponding alcohol and carbonyl compound. This reaction is reversible.

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.
