(a) Interpretation: The carbonyl compound, and diol needed to prepare the given compound are to be stated. Concept introduction: Both aldehydes and ketones yield acetal, when they are treated with diols in the presence of aqueous acidic media. Acetals are the groups in which carbon atom is bonded to two OR groups through single bonds. They are used as protecting groups as they are stable enough in neutral to strong basic condition.

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.
