Using formaldehyde as the only source of carbon, the formation of the given compound has to be found. Concept Introduction: Acetals: Generally Acetals are used to protect the ketone and aldehyde (carbonyl group). In this reaction acetone is protected as acetal by using ethylene glycol. Generally acetals are less stable compound. In acidic condition, an aldehyde or a ketone reacts with two molecules of alcohol or a molecule of diol to form acetal or cyclic acetal respectively. General scheme:

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.
