in the esterification synthesis of isopentyl acetate, why is CO2 produced during the extraction procedure after
the addition of Na2CO3? Write a balanced equation of the reaction
Step by step
Solved in 2 steps
- For the esterification synthesis of isopentyl acetate, acetic acid is one of the component used to prepare the product. why is there a need to add sulfuric acid to the solution if acetic acid is already an acid?A lighted matchstick touched the Toluene solution, it catched the fire and immediately turned off, Why does the sooty burning took place after the reaction?State various conditions required in preparation of H2SO4?
- In esterification reaction of isopentyl acetate, What is the purpose of the reflux setup in the synthesis of the liquidester?Give the mechanism in the process of esterification. How is water formed in the reaction?in the esterification of acetylsalicylic acid phosphoric acid was used as a catalyst. Hydrochloric acid is about as strong a mineral acid as sulfuric acid. Why would HCl be not a satisfactory catalyst in this reaction?
- Can azeotropes be separated using simple distillation? Why or why not?A mixture containing compounds A and B in methylene chloride (CH2Cl2) was extracted in a separatory funnel containing aqueous HCl. Which compound migrates to the aqueous layer? Why?in the synthesis of benzocaine: what is the structure of the precipitate that formed after the sulfuric acid was added to the cooled mixture of p-aminobenzoic acid and pure ethanol?
- The pKas of chemicals HX and HY are 5 and 7 respectively. The pKa of carbonic acid H2CO3is 6. If you made up an ether solution of chemicals HX and HY in a separatory funnel, andthen added an aqueous solution of sodium bicarbonate NaHCO3 to that separatory funnel,would both HX and HY stay in the ether layer? Or would either or both of them transfer intothe aqueous layer? If one goes into the water layer, will it be in it’s neutral HX/HY form, or init’s deprotonated anionic form?1. What is the reason behind the portion-by-portion evaporation of DCM in the extraction of eugenol? 2. Enumerate some pharmaceutical and medical uses of eugenol 3. What does the ferric chloride test identify? Is it specific test for eugenol? Why or why not?What is the purpose of adding Na2CO3 into the collected tea extract beforeextraction with CH2Cl2?
