In a set of reactions, acetic acid yielded a product D.
CH3COOH A B C D
The structure of D would be
Aldehydes or ketones are treated with-bromo ester in the presence of zinc to form -hydroxy ester followed by dehydration to form ,-unsaturated ester.This reaction is known as:
Witting reaction.
Tischenko reaction.
Reformatsky reaction.
Crossed-cannazzaro's reaction.
C.
Reformatsky reaction.
Organic zinc is used because it is less reactive than Grignard reagent and prevents second nucleophilic addition to the ester group.
The correct structure of the stable compound which is obtained when acetophenone react with a base C2H5OH is
