Question

The textbook mentions that Grignards react with carbon dioxide. In fact, this is done intentionally in experiment 19.4B, the Preparation of Benzoic Acid. In our experiment, we are not concerned about our Grignard reacting with carbon dioxide in the atmosphere because our reactions are performed in the hoods or under "elephant trunks" where the strong local exhaust conditions eliminate any carbon dioxide in the vicinity of our apparatus the reaction with carbon dioxide requires much higher temperatures than what we are using the diethyl ether we are using as a solvent is so volatile that, under reflux conditions, it essentially displaces all of the air in the reaction flask and condenser our reactions are performed under a nitrogen atmosphere

Explanation / Answer

Option c is correct

Explanation-In the preparation of benzoic acid, we are not concerned about our Grignard reacts with CO2 in atmosphere because diethyl ether which is used as solvent for the Grignard reaction is highly volatile. Under reflux condition, it displaces all air in the reaction flask and condenser.
