The correct Answer is:
To solve the question "The compound which can give Amine with KOH and Br2 is-", we will follow these steps: ### Step 1: Understand the Reaction The reaction in question refers to the Hofmann's bromamide reaction, where a primary amide reacts with bromine (Br2) in the presence of a strong base like potassium hydroxide (KOH) to produce a primary amine. The general reaction can be represented as follows: \[ RCONH_2 + Br_2 + 4KOH \rightarrow RNH_2 + 2KBr + K_2CO_3 + 2H_2O \] ### Step 2: Identify Primary Amide To identify the correct compound that can undergo this reaction, we need to look for a primary amide (RCONH2) in the given options. A primary amide has the structure where the carbonyl group (C=O) is directly attached to a nitrogen atom that is bonded to one hydrogen atom and one carbon chain. ### Step 3: Analyze the Options 1. **Option A**: A secondary amine (R2NH) - This cannot undergo the Hofmann reaction. 2. **Option B**: A tertiary amine (R3N) - This also cannot undergo the Hofmann reaction. 3. **Option C**: A primary amide (RCONH2) - This is the correct structure we are looking for. 4. **Option D**: A compound that does not have the CONH2 group. ### Step 4: Conclusion Among the options, the only compound that can give an amine with KOH and Br2 is the one that contains the primary amide functional group (RCONH2). Therefore, the answer is the compound that corresponds to the primary amide. ### Final Answer The compound which can give Amine with KOH and Br2 is the primary amide (RCONH2). ---
