State the crossed aldol condensation of acetaldehyde

Reference no: EM13174482

The crossed aldol condensation of acetaldehyde with benzaldehyde is aided by the fact that benzaldehyde bears no α-protons. However, a possible competitive reaction is the “selfcondensation†of two molecules of acetaldehyde. Slow addition of the acetaldehyde to a benzaldehyde solution containing an NaOH/ethanol/water mixture will often result in less self-condensation. Explain.
