The Correct Option is B
Solution and Explanation
Concept:
Hell-Volhard-Zelinsky (HVZ) reaction introduces a halogen atom at the \(\alpha\)-carbon atom of a carboxylic acid.
Step 1: Write the general reaction.
\[ RCH_2COOH \xrightarrow{Cl_2/P} RCHClCOOH \] or \[ RCHBrCOOH \] depending on the halogen used.
Step 2: Identify the product.
The reaction specifically produces an \(\alpha\)-halo acid. Therefore the product is \[ RCH(Cl)COOH \] \[ \boxed{\text{Answer = (B)}} \]
