o.lqu3 4. During Part 2 of the experiment, why are drops of the reaction mixture placed in a test tube containing dichloromethane and 10% sodium bicarbonate at 5-minute intervals? (2pts) 5. Briefly state the objective for each step in the experiment and how the outcome of each step will be determined. What should you see in the data to prove the identity of the alcohol formed during the Grignard and the alkenes formed from the dehydration of the alcohol? For example, how many 15C and 'H NMR absorbencies and what molecular weight should be observed in the Ms. What functional groups and frequencies would you expect for the IR?

Explanation / Answer

4. That is called sampling(workup). reaction mixture has to place in suitable organic solvent(here dichloromethane) and neutralize with a mild base(here 10%NaHCO3) and to be submit for analysis or you can yourself check with TLC.
