Oxidation of organic compound 'A' with Na2Cr2O7 and H2SO4 gives compound 'B', which on reduction with H2 in the presence of Ni catalyst gives ethyl alcohol. Give the name of compound 'A'.

Question

Oxidation of organic compound 'A' with Na2Cr2O7 and H2SO4 gives compound 'B', which on reduction with H2 in the presence of Ni catalyst gives ethyl alcohol. Give the name of compound 'A'. (A) ethanal (B) ethanol (C) ethanoic acid (D) ethene

Tardigrade Admin · Accepted Answer

A xrightarrow[[O]]Na2Cr2O7 / H2SO4 B xrightarrowH2 / Ni Ethyl alcohol Compound Bon reduction with H2 in the presence of Ni gives ethyl alcohol, it means compound B is ethanal or ethanoic acid; because aldehyde or acid on reduction gives primary alcohol. Again, compound B is obtained by the oxidation of A, it means A is ethanol, because primary alcohol on oxidation gives aldehyde or acid.
