(a) Interpretation: The hemiacetal and acetal formed when the given ketone reacts with two equivalents of CH 3 OH in the presence of H 2 SO 4 needs to be drawn. Concept introduction: Ketones react with alcohols and form hemiacetals in the presence of an acidic medium if the ratio between the ketone and the alcohol is 1:1. If the ratio between a ketone and the alcohol is 2:1, acetals are formed.

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.
