Key concept: Hinsberg reagent test

Hinsberg reagent is benzenesulphonyl chloride ($\mathrm{C_6H_5SO_2Cl}$). It reacts with amines containing at least one N–H bond to form sulphonamides.

• 1° amines react to form sulphonamides.
• 2° amines also react to form sulphonamides.
• 3° amines do not react to form sulphonamides because nitrogen has no hydrogen attached.

What is being asked?

We need the product among the given reaction products that does not react with Hinsberg reagent to form sulphonamide.

Therefore, we must identify the product that is a tertiary amine.

Inference from the stored answer

The problem statement as provided does not include the actual reaction schemes or structures for options $A, B, C, D$; the options are blank. So the chemical structures of the products cannot be independently analyzed from the given text.

Using the principle

Since only a tertiary amine fails to give sulphonamide in Hinsberg test, the correct option must correspond to the tertiary amine product.

Comparison with stored correct answer

The stored correct answer is B. Hence, option B must be the product that is a tertiary amine and therefore does not react with Hinsberg reagent to form sulphonamide.

Final conclusion

The product that does not react with Hinsberg reagent to form sulphonamide is: $\boxed{B}$
