Chemistry - Carbonyl compounds Question with Solution | TestHub

Compound $A$ (molecular formula ${\mathrm{C}}_3{\mathrm{H}}_8\mathrm{O}$ ) is treated with acidified potassium dichromate to form a product $B$ (molecular formula ${\mathrm{C}}_3{\mathrm{H}}_6\mathrm{O}$ ). $B$ forms a shining silver mirror on warming with ammoniacal silver nitrate. $B$ when treated with an aqueous solution of ${\mathrm{H}}_2{\mathrm{NCONHNH}}_2.\mathrm{HCl}$ and sodium acetate gives a product $C$. Identify the structure of $C$.
