Document Summary
You must type directly into the answer boxes of the report template. Font or size-altered answer boxes will receive a mark of zero. Structures may be written by hand in pen. Pencil, erasable pen or white-out is not permitted. Please explain the difference between a self aldol condensation and a mixed aldol condensation. Self aldol condensation is where the carbonyl groups acts as both the nucleophile and electrophile. Mixed aldol condensation is where the electrophile and nucleophile are different species. (1 mark) In order to have a successful mixed aldol condensation, describe two requirements of the. In order to have a successful mixed aldol condensation, aldehydes must be more reactive then ketones as they act as the nucleophile. Secondly, aldehydes lacking alpha hydrogen"s can only function as acceptor recipients, because they have no hydrogen"s to give up. This will ultimately limit the amount of products that can be formed. reaction conditions that should be met? (1. 5 marks)
