Question

What are \(X\) and \(Y\) respectively in the following reaction sequence?

• A. \(X=\) 3-Phenylpropanoic acid,\(Y=\) \(p\)-Bromobenzoic acid
• B. \(X=\) 2-Phenylpropanoic acid,\(Y=\) \(p\)-Bromobenzoic acid
• C. \(X=\) 2-(4-Bromophenyl)propanoic acid,\(Y=\) Benzoic acid
• D. \(X=\) 3-Phenylpropanoic acid,\(Y=\) Benzoic acid

Hint:

Remember: \[ \boxed{ \mathrm{ArCH_2Br} \xrightarrow{\mathrm{Mg}} \mathrm{ArCH_2MgBr} \xrightarrow{\mathrm{CO_2/H_3O^+}} \mathrm{ArCH_2COOH} } \] Benzylic bromination occurs with \[ \boxed{\mathrm{Br_2/h\nu}.} \]

Answer 1

The Correct Option is B
