The Correct Option is A
Solution and Explanation
Concept:
Ketones react with hydrazine (\( \text{NH}_2\text{NH}_2 \)) through a condensation reaction to form hydrazones.
In this reaction, the oxygen atom of the carbonyl group is replaced by the \( \text{NNH}_2 \) group.
Step 1: Write the general reaction. \[ R_2C=O + NH_2NH_2 \rightarrow R_2C=NNH_2 + H_2O \]
Step 2: Identify the product. The product formed is called a hydrazone.
Step 3: Final result. \[ \boxed{\text{Hydrazone}} \]
Step 1: Write the general reaction. \[ R_2C=O + NH_2NH_2 \rightarrow R_2C=NNH_2 + H_2O \]
Step 2: Identify the product. The product formed is called a hydrazone.
Step 3: Final result. \[ \boxed{\text{Hydrazone}} \]
