A possible competitive reaction is the “self-condensation” of two molecules of acetaldehyde. Slow addition of the acetaldehyde to a benzaldehyde solution containing the base will often result in less self-condensation. Explain. Identify one other method that can be used to combat this competitive reaction. with online website source
Accepted Answer
The slow addition of acetaldehyde to a benzaldehyde solution containing a base minimizes self-condensation because it limits the concentration of acetaldehyde at any given time. This reduces the likelihood of two acetaldehyde molecules encountering each other and undergoing the self-condensation reaction.
One other method to combat this competitive reaction is to use a catalyst that is more selective for the desired aldol condensation reaction with benzaldehyde. This catalyst would preferentially bind to benzaldehyde, making it more reactive and reducing the chances of acetaldehyde self-condensation.
