Identify the product obtained when ketone reacts with NH ₂ - NH ₂ .
Options
- AAniline
- BHydrazone
- CPhenyl hydrazone
- DAnisole
Correct answer
B. Hydrazone
Step-by-step solution
Ketones react with hydrazine ( H₂N-NH₂ ) to form hydrazones. The reaction proceeds via nucleophilic addition of hydrazine to the carbonyl group, followed by the elimination of a water molecule. R₂C=O + H₂N-NH₂ R₂C=N-NH₂ + H₂O The resulting product, R₂C=N-NH₂ , is known as a hydrazone. Answer: Hydrazone
