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

Question

On oxidation of organic compound A with Na2Cr2O7 and H2SO4 gives compound B, which on reduction with H2 in 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 xrightarrow[]H2/Ni Ethyl alcohol Compound B on reduction with H2/ in presence of Ni given ethyl alcohol it means compound B is ethanal, because aldehyde on reduction gives primary alcohol. Again compound B obtained from oxidation of A it means A is ethanol, because primary alcohol on oxidation gives aldehyde. underset(A) mathopCH3-CH2-OH xrightarrow[[O]]Na2Cr2O7/H2SO4 underset(B) mathopCH3- oversetO mathop overset| | mathopC -H xrightarrowH2/Ni undersetethyl alcohol or ethanol mathopCH3-CH2-OH
