An organic compound ( X ) is oxidised by using acidified ( K ₂ Cr ₂ O ₇ ) solution. The product obtained reacts with phenyl hydrazine but does not answer silver mirror test. The compound ( X ) is,

Step-by-step solution

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
