What is the purpose of adding a boiling chip during heating? How does it help?
Adding acetophenone slowly to a cold solution of LDA produces the enolate of acetophenone, but adding LDA slowly to a cold solution of acetophenone produces a condensation product. Draw the resonant structures that result from adding acetophenone to cold solution of LDA.
Adding acetophenone slowly to a cold solution of LDA produces the enolate of acetophenone; but adding LDA slowly to a cold solution of acetophenone produces a condensation product. Draw the aldol product that results from the slow addition of LDA to acetophenone.
What is the purpose of adding water after cooling the reaction mixture in this experiment? I understand it is to precipitate the product, but what exactly does water do in this, what impurity does it get rid of and how? Mesostillbenedibromide crude with KOH and triethyl glycol in a double elimination to produce Diphenylacetylene. Water is added after the reaction mixture is cooled. Then it is put through vacuum filtration, and further recrystallized with 7:3 etoac:water in a hot water...
