Products of aldol condensation

WebbAldol condensation is the removal of a water molecule from the aldol product while an aldol addition is where a ketone or aldehyde enolate is added to a carbonyl. Aldehydes are more reactive than ketones due to the lack of an alpha hydrogen and having only one electron donor group. WebbIn crossed aldol condensation，in order to avoid unwanted product mixture，the compound without alpha hydrogen like benzaldehyde can be a good choice. Why？？？does it means that two enolate will produce unwanted product mixture？ 1. what is unwanted product mixture ？ 2. and what is wanted product？
