Compound 'A' (molecular formula `C_3H_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 ammoniacal silver nitrate. 'B'when treated with an aqueous solution of `H_2NCONHNH_2, HCl and `sodium acetate gives a product 'C'. Identify the structure of C :

Options

A. `CH_(3)CH_(2)CH=N NHCONH_(2)`
B. `CH_(3)underset(CH_(3))underset(|)(C)=NHHCONH_(2)`
C. `CH_(3)underset(CH_(3))underset(|)(C)=NCONHNH_(2)`
D. `CH_(3)CH_(2)CH=NCONHNH_(2)`

Answer

A

Explanation
