The open-chain structure of each of the given compounds is to be determined. Concept introduction: Ketones react with diols to form acetals. This reaction is generally used as a protecting group of the carbonyl group in a reaction and then through hydrolysis, the respective carbonyl group can be generated back. Aldehydes react with diols to form hemiacetals. The reaction takes place in the presence of an acid. The formation of acetals and hemiacetals is a type of nucleophilic substitution reaction.

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.
