COMEDK · Chemistry · 27. Aldehydes and Ketones
Two statements, one Assertion (A) and the other Reason (R) are given. Choose the correct option.
Assertion: Compound \([\mathrm{X}]\) reacts with Hydrazine in presence of \(\mathrm{KOH} /\) Glycol to form the product \([\mathrm{Y}]\).
- A Both A and R are correct and R is the correct explanation of A .
- B Both \(A\) and \(R\) are correct but \(R\) is not the correct explanation of \(A\).
- C A is wrong but R is correct.
- D \(A\) is correct but \(R\) is wrong.
Answer & Solution
Correct Answer
(A) Both A and R are correct and R is the correct explanation of A .
Step-by-step Solution
Detailed explanation
The reaction shown is the Wolff-Kishner reduction, which uses hydrazine (\(NH_{2}NH_{2}\)) in the presence of a strong base like \(KOH\) and a high-boiling solvent like ethylene glycol to reduce a carbonyl group (aldehyde or ketone) to a methylene group (\(-CH_{2}-\)). In the…
