ChemistryOrganic Oxidation & Reduction ReactionsJEE Main

Compound A (molecular formula C₃H₈O) is treated with acidified potassium dichromate to form a product B (molecular formula C₃H₆O). B forms a shining silver mirror on warming with ammoniacal silver nitrate. B when treated with an aqueous solution of H₂NCONHNH₂·HCl and sodium acetate gives a product C. Identify the structure of C.

Answer: (A)

Solution

A (C₃H₈O, oxidizable to an aldehyde) is the primary alcohol 1-propanol; oxidation gives propanal, CH₃CH₂CHO (B, C₃H₆O), which gives a positive Tollens' test. B
