Write the balanced equation for the formation of benzoic acid from the Grignard reagent. Include all reagents and products but not solvents.

The correct answer is - C6H5MgBr + CO2  → C7H6O2 (without solvent)

Explanation:

Grignard reagents are the reagents formed by the chemical reaction between magnesium with an alkenyl or alkyl halide which are represented by the chemical formula RMgX where X stands for the halogen, and R is an alkyl or aryl group. These alkyl or aryl groups are based on the benzene ring.

The nature of these reagents are nucleophilic react with electrophiles such as epoxides or carbonyl groups. The formation of benzoic acid is possible with the reaction of the Grignard reagent with the carbon dioxide In H3O+ to form benzoic acid with MgBrOH.

C6H5MgBr + CO2 → C7H6O2
