In the list below, identify all the approved ways to stimulate Grignard formation during the laboratory procedure:

a) Adding the Grignard reagent dropwise to the reaction mixture
b) Stirring the reaction mixture vigorously
c) Maintaining the reaction mixture at a high temperature
d) Using anhydrous solvents and reagents

Answer :

Final answer:

The correct options are a) Adding the Grignard reagent dropwise to the reaction mixture, and d) Using anhydrous solvents and reagents. The answer discusses approved methods for stimulating Grignard formation in a laboratory setting such as adding the reagent dropwise and using anhydrous solvents.

Explanation:

The correct options are a) Adding the Grignard reagent dropwise to the reaction mixture, and d) Using anhydrous solvents and reagents. Approved ways to stimulate Grignard formation:

  1. Adding the Grignard reagent dropwise to the reaction mixture
  2. Using anhydrous solvents and reagents

Non-approved methods: Maintaining high temperatures can hinder Grignard formation. Stirring vigorously may lead to excessive alcohol formation. Therefore, a Grignard reagent should be added dropwise to ensure a controlled reaction. Anhydrous solvents prevent unwanted side reactions.
