- Draw the structure of the product formed in the following directed aldol reaction. Stereochemistry can be ignored. 1) LDA 2) 3) H₂OWhich of the following statements describes the FIRST STEP in the mechanism of the aldol condensation? O A hydrogen on a carbon alpha to a C=O is abstracted by an acid to give the enolate anion. O A nucleophilic base attacks the carbonyl carbon atom. O The carbonyl oxygen is protonated by the base ion. O The carbonyl oxygen of one aldehyde attacks the carbonyl carbon of another. O A hydrogen on a carbon alpha to a C=O is abstracted by a base to give the enolate anion.The aldol double condensation reaction is highly selective for formation of a single double condensation product. Explain why only one aldol condensation product is formed despite two carbonyl compounds being present for the reaction.
