Question

For this experiment you should start heating water in a large beaker but under no circumstance should you place any hexanes near the heater! In fact, you should not get the total quantity of hexanes that you will use in the experiment, only the small amount you need for each trituration and keep it on the opposite side of the hood as the heater. You should weigh out the largest round bottom flask that you have with the aid of a cork ring. You will then clamp the flask that contains the dried products from the previous lab, add the appropriate amount of hexanes away from the heater, heat the mixture a short time on the hot water bath (Bain-Marie or Baño Maria) until the hexanes start boiling (you are not trying to evaporate it), and decant off the supernatant carefully into your largest round bottom flask away from the heater with the aid of a funnel suspended on a ring clamp. Since you are repeating the trituration a few times you should not try to pour off all the supernatant at the nsk of pour n ove?solid. The hexanes will be evaporated off on a rotary evaporator. Once evaporated and cooled off you should weigh the flask and remove your product for the next reaction. What is our major concern for this experiment? Select one: Oa. fire b. isolating the greatest amount of product c.exposure to fumes d. spilling the product O e. contamination of the product The desired product from this experiment is Select one: 0 a. insoluble in the hexanes O b. is soluble in hexanes

Explanation / Answer

ans)

from above information

the major concern for this experiment is

option b

isolating the greatest amount of product

because in this experiment we can isolate good amount of products by removing the contaminants
