Interpretation : We need to interpret the formation of benzene as the side product during the Grignard reaction while using phenyl magnesium bromide with the help of a balanced chemical equation.
Concept Introduction : Grignard reagent is a chemical compound with a general formula
The Grignard reagent is widely used in the
Answer to Problem 1Q
The hydrolysis of phenyl magnesium bromide forms benzene as the side product. The balanced chemical equation can be written as:
Explanation of Solution
In the Grignard reagent, the alkyl or aryl group acts as a strong nucleophile therefore it can react easily with carbonyl compounds to form alcohols. It can readily react with water that breaks the
Thus, hydrolysis of phenyl magnesium bromide forms benzene as a side product. This can occur if the glassware is not completely dry. The balanced chemical equation can be written as:
Grignard reagent is unstable in water and readily decomposes to alkane and respective alcohol.
