When compound \(X\) is oxidised by acidified potassium dichromate, compound \(Y\) is formed. Compound \(Y\) on reduction with \(\mathrm{LiAlH}_4\) gives \(X . X\) and \(Y\) respectively are :
- A \(\mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}, \mathrm{CH}_3 \mathrm{COOH}\)
- B \(\mathrm{CH}_3 \mathrm{COCH}_3, \mathrm{CH}_3 \mathrm{COOH}\)
- C \(\mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}, \mathrm{CH}_3 \mathrm{COCH}_3\)
- D \(\mathrm{CH}_3 \mathrm{CHO}, \mathrm{CH}_3 \mathrm{COCH}_3\)
Answer & Solution
Correct Answer
(A) \(\mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}, \mathrm{CH}_3 \mathrm{COOH}\)
Step-by-step Solution
Detailed explanation
When ethyl alcohol is oxidised by acidified potassium dichromate, \(\mathrm{CH}_3 \mathrm{COOH}(\mathrm{Y})\) is obtained as : \(3 \mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}(X)+2 \mathrm{~K}_2 \mathrm{Cr}_2 \mathrm{O}_7+8 \mathrm{H}_2 \mathrm{SO}_4 \longrightarrow\)…
