Rate Of A Chemical Reaction

To solve this matching question, we need to associate each item from List-I with the correct option from List-II based on their known chemical reactions and applications. Let's go through each option step by step:

1. Benzene sulphonyl chloride is known as the Hinsberg reagent. It is used for the test of amines, particularly to distinguish between primary, secondary, and tertiary amines. Therefore, A matches with III.
2. The Hoffmann bromamide reaction is a well-known reaction that converts an amide into an amine with the loss of a carbon atom. This reaction also involves the formation of an isocyanate intermediate. Hence, B matches with IV.
3. The Carbylamine reaction is a test for primary amines. It involves the formation of an isocyanate intermediate and produces a foul-smelling compound when primary amines are treated with chloroform and an alcoholic base. So, C matches with I.
4. Hoffmann orientation leads to anti-Saytzeff orientation in elimination reactions. This means that the less substituted alkene (less stable) is formed in preference to the more substituted one. Thus, D matches with II.

Based on the above associations, the correct matching is:

• A - III
• B - IV
• C - I
• D - II

Therefore, the correct answer is:
