`C_(6)H_(5)CHO overset(Cl_(2))(rarr)` A + HCl
The product A when reacts with the following compounds the reaction is known as Schotten Baumann reaction –

Options

A. `C_(6)H_(5)NH_(2)`
B. `C_(6)H_(5)CH_(2)`OH
C. `C_(6)H_(5)`OH
D. All of these

Answer

To solve the question step by step, we will analyze the reaction of benzaldehyde with chlorine and identify the product A, which is involved in the Schotten-Baumann reaction.

### Step 1: Identify the Reactant
The given reactant is benzaldehyde, represented as \( C_6H_5CHO \).

### Step 2: Reaction with Chlorine
When benzaldehyde reacts with chlorine (\( Cl_2 \)), it undergoes chlorination. The reaction can be represented as:
\[ C_6H_5CHO + Cl_2 \rightarrow A + HCl \]
In this reaction, the chlorine atom replaces the hydrogen atom of the carbonyl group, resulting in the formation of benzoyl chloride (\( C_6H_5C(O)Cl \)).

### Step 3: Identify Product A
The product \( A \) formed from the reaction is benzoyl chloride, which can be represented as:
\[ A = C_6H_5C(O)Cl \]

### Step 4: Understand the Schotten-Baumann Reaction
The Schotten-Baumann reaction involves the reaction of acid chlorides with amines to form amides. In this case, benzoyl chloride (product \( A \)) will react with an amine.

### Step 5: Identify the Reactant for Schotten-Baumann Reaction
To proceed with the Schotten-Baumann reaction, we need to identify an amine that will react with benzoyl chloride. Among the options provided, we look for an amine.

### Step 6: Reaction of Benzoyl Chloride with Amine
The reaction of benzoyl chloride with an amine can be represented as:
\[ C_6H_5C(O)Cl + RNH_2 \rightarrow C_6H_5C(O)NR + HCl \]
Where \( RNH_2 \) is the amine. The product will be an amide.

### Conclusion
The correct answer to the question is the amine that will react with benzoyl chloride in the Schotten-Baumann reaction.

### Final Answer
The product \( A \) when reacts with an amine will undergo the Schotten-Baumann reaction.
