• CH₃C$\equiv \mathrm{N}$

• CH₃CH₂.OH

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
