An organic compound \( \mathrm{X} \) is oxidised by using acidified \( \mathrm{K}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7} \) solution. The product obtained
reacts with phenyl hydrazine but does not answer silver mirror test. The compound \( X \) is,
- A 2-propanol
- B Ethanal
- C Ethanol
- D \( \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{3} \)
Answer & Solution
Correct Answer
(A) 2-propanol
Step-by-step Solution
Detailed explanation
In the question, the oxidation product of organic compound \( (X) \) do not answer silver mirror test but react with phenyl
hydrazine,
No silver mirror test
therefore, \( X \) is propan-2-ol, which on oxidation give acetone which further react with phenyl hydrazine to give acetone
phenylhydrazone, but not react give silver mirror test. The reactions involved are
Acetone phenylhydrazone
hydrazine,
No silver mirror test
therefore, \( X \) is propan-2-ol, which on oxidation give acetone which further react with phenyl hydrazine to give acetone
phenylhydrazone, but not react give silver mirror test. The reactions involved are
Acetone phenylhydrazone
