plain the chemical importance of the product from the first step? Explain about two layers in step 11. Which layer is on top in a separatory funnel? Why? Draw the structure of the product in the ether layer of step 12.
Catalysis and Enzymatic Reactions
Catalysis is the kind of chemical reaction in which the rate (speed) of a reaction is enhanced by the catalyst which is not consumed during the process of reaction and afterward it is removed when the catalyst is not used to make up the impurity in the product. The enzymatic reaction is the reaction that is catalyzed via enzymes.
Lock And Key Model
The lock-and-key model is used to describe the catalytic enzyme activity, based on the interaction between enzyme and substrate. This model considers the lock as an enzyme and the key as a substrate to explain this model. The concept of how a unique distinct key only can have the access to open a particular lock resembles how the specific substrate can only fit into the particular active site of the enzyme. This is significant in understanding the intermolecular interaction between proteins and plays a vital role in drug interaction.

1. CO2
Et,0
2. H3O*
Procedure:
8. Avoid moisture and add crushed 10 g dry ice into EF.
9. Pour the product mixture over dry ice and swirl for 10 min.
10. Add 10 mL water, then 10 mL 3M H2SO4 with 5 g ice.
11. Make total volume around 20 mL by adding ether. Separate two layers
12. Extract aqueous layer with ether (3X5ML). Combine and keep the ether layer.
13. Extract the ether layer with 1M NaOH(aq) and keep the aqueous layer.
14. Adjust pH to 3 of the above aqueous layer and keep it in ice bath.
15. Filter the precipitation and dry it in your drawer.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0a629cc1-0cec-4726-962d-d2bbbc823631%2Fd55128c7-1c72-4107-9cb9-e261bcd8a9b4%2Fo7if6ie_processed.png&w=3840&q=75)
