MCQ
Compound $A$ (molecular formula $C_3 H_8O$) is treated with acidified potassium dichromate to form a product $B$ (molecular formula $C_3H_6O$). $B$ forms a shining silver mirror on warming with ammonical silver nitrate, $B$ when treated with an aqueous solution of $NH_2NHCONH_2$ and sodium acetate gives a product $C$. Identify the structure of $C$.
