Circle the protected carbonyl group in the given reaction, and draw the structure of the product. Concept introduction: For the protection of the ketone or aldehyde , ethylene glycol is used; this results in the formation of the acetal. Acetal is deprotected in the presence of water, and strong acid like sulfuric acid (H 2 SO 4 ) results in the reformation the carbonyl group (C=O ) .

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.

Draw the reactant of the following reaction sequence.

Draw a complete, step-wise, curved arrow mechanism for each reaction shown below. You don't need to worry about stereochemistry for these problems. It may help if you take the following steps. 1) Find the nucleophile and the electrophile. 2) Determine the major functional group present in the nucleophile and electrophile. 3) Determine the type of reaction this particular nucleophile/electrophile pair is likely to participate in 4) Draw the mechanism that corresponds with this reaction type. a) OH cat.
