WILL RATE!! DUE IN 5 HOURS.. there are multiple posts from me, all from this lab.

I will make sure u get rated for your efforts!!! thanks

5. Why is the solution of aldehyde added to the Grignard reagent in a dropwise fashion rather than added all at once?

7. Why is technical rather than anhydrous diethyl ether used in the work-up procedure?

8. Why is hydrolysis of the reaction mixture performed with aqueous sulfuric acid that is cold rather than at room temperature?

8) The grignards reagent is stable only at low temperature, its 0-5 o c

so we carry out the reaction at low temaperature..

please post remaining questions sepaartely
