The full mechanism of the crossed aldol condensation reaction that was performed in this lab involves the following steps: Step 1: Protonation of the carbonyl oxygen of acetone by HCl, followed by addition of benzaldehyde to form an enolate intermediate. Step 2: Attack of the enolate intermediate on the ... codec audio windows 10 softonic WebThe overall process is then referred to as an "aldol condensation". The example using ethanal shown above only involves one starting material and is therefore referred to as a "self condensation". "Mixed" or "crossed" aldol condensations occur when two different molecules containing carbonyl groups are combined.
