An unknown compound D first oxidized to aldehyde and then acetic acid by a dilute solution of K 2 Cr 2 O 7 and H 2 SO 4. The compound D is (A)  CH3OH  (B)  C2H5OH  (C)  CH3CH2COOH  (D)  CH3CH2CHO

D xrightarrow textOxidation aldehyde xrightarrow[ H 2 SO 4] K 2 Cr 2 O underset text Acetic acid CH 3 COOH 1° alcohol on oxidation gives aldehyde having same number of carbon and aldehyde on oxidation gives acid having same number of carboñ atoms. It means, D will be alcohol having two carbon atoms that is C 2 H 5 OH (ethyl alcohol) and the alcohol on oxidation will give CH 3 CHO (acetaldehyde) underset(D)C 2 H 5 O H xrightarrow text [O] CH 3 CHO xrightarrow[ O ] CH 3 COOH
