The Aldol Condensation: Synthesis of Dibenzalacetone. Percentage yield : 78.1 % The % recovery : 42.4 % 1. why does the % recovery lower than % yield ？ 2. does it indicate the loss of the product during the process of recrystallization？ 3. what are some other possible experimental （source）error or factors which made % recovery to be so low？
