- Alcohols
- Hydrazones
- Alkenes
Show Solution
The Correct Option is C
Solution and Explanation
Step 1: Reagent
The reagent is hydrazine, which condenses with the C=O group.
Step 2: Product
Condensation with loss of water forms C=N-NH$_2$, a hydrazone.
Step 3: Match the Option
The first-step compound is therefore a hydrazone.
Final Answer:
The intermediate formed first is a hydrazone. \[ \boxed{\text{(C) }\text{Hydrazones}} \]
