Question
Which of the following reagents can be used to convert a Grignard reagent (RMgX) into a carboxylic acid?Select answer from the options belowNa2Cr2O7, H2SO4, H2O1) CO2 , 2) H3O+H3O+, heat1) O3 , 2) H2O
Solution
The correct reagents to convert a Grignard reagent (RMgX) into a carboxylic acid are: 1) CO2 , 2) H3O+.
Here's the step by step process:
-
The Grignard reagent (RMgX) reacts with carbon dioxide (CO2). This forms a magnesium salt of the carboxylic acid.
-
The magnesium salt is then treated with a strong acid, in this case, hydronium ion (H3O+). This step protonates the carboxylate salt, converting it into the desired carboxylic acid.
So, the correct answer is CO2 , H3O+.
